Botanical Name : Melaleuca alternifolia/Melaleuca leucadendron, M. leucadendra Family: Myrtaceae Subfamily: Myrtoideae Genus: Melaleuca Kingdom: Plantae Division: Magnoliophyta Class: Magnoliopsida Order: Myrtales Tribe: Melaleuceae Syn. : Melaleuca minor Common Names : Tea Tree , ti tree,Narrow-leaved Paperbark, Narrow-leaved Tea-tree, Narrow-leaved Ti-tree, or Snow-in-summer, Cajeput Oil , Weeping tea tree, weeping paperbark
Habitat : There are well over 200 recognised species, most of which are endemic to Australia. A few species occur in Malesia and 7 species are endemic to New Caledonia.
Description:
The species are shrubs and trees growing (depending on species) to 2–30 m (6.6–98 ft) tall, often with flaky, exfoliating bark. The leaves are evergreen, alternately arranged, ovate to lanceolate, 1–25 cm (0.39–9.8 in) long and 0.5–7 cm (0.20–2.8 in) broad, with an entire margin, dark green to grey-green in colour. The flowers are produced in dense clusters along the stems, each flower with fine small petals and a tight bundle of stamens; flower colour varies from white to pink, red, pale yellow or greenish. The fruit is a small capsule containing numerous minute seeds.Leaves are linear, 10-35 mm long and 1 mm wide. White flowers occur in spikes 3-5 cm long. Small woody, cup-shaped fruit are 2-3 mm in diameter.
Melaleuca is closely related to Callistemon, the main difference between the genera being that the stamens are generally free in Callistemon but grouped into bundles in Melaleuca.
In the wild, Melaleuca plants are generally found in open forest, woodland or shrubland, particularly along watercourses and the edges of swamps.
The best-accepted common name for Melaleuca is simply melaleuca; however most of the larger species are also known as paperbarks, and the smaller types as honey myrtles. They are also sometimes referred to as punk trees.
One well-known melaleuca, the Ti tree (aka tea tree), Melaleuca alternifolia, is notable for its essential oil which is both anti-fungal, and antibiotic, while safely usable for topical applications. This is produced on a commercial scale, and marketed as Tea Tree Oil. The Ti tree is presumably named for the brown colouration of many water courses caused by leaves shed from trees of this and similar species (for a famous example see Brown Lake (Stradbroke Island)). The name “tea tree” is also used for a related genus, Leptospermum. Both Leptospermum and Melaleuca are myrtles of the family, Myrtaceae.
In Australia, Melaleuca species are sometimes used as food plants by the larvae of hepialid moths of the genus Aenetus including A. ligniveren. These burrow horizontally into the trunk then vertically down.
Melaleucas are popular garden plants, both in Australia and other tropical areas worldwide. In Hawai?i and the Florida Everglades, Melaleuca quinquenervia (Broad-leaved Paperbark) was introduced in order to help drain low-lying swampy areas. It has since gone on to become a serious invasive weed with potentially very serious consequences being that the plants are highly flammable and spread aggressively. Melaleuca populations have nearly quadrupled in southern Florida over the past decade, as can be noted on IFAS’s SRFer Mapserver
The genus Callistemon was recently placed into Melaleuca.
Weeds
Melaleucas were introduced to Florida in the United States in the early 20th century to assist in drying out swampy land and as garden plants. Once widely planted in Florida, it formed dense thickets and displaced native vegetation on 391,000 acres (1,580 km2) of wet pine flatwoods, sawgrass marshes, and cypress swamps in the southern part of the state. [It is prohibited by DEP and listed as a noxious weed by FDACS.]
Melaleucas became an invasive species that raised serious environmental issues in Florida’s Everglades and damaged the surrounding economy. Agricultural Research Service (ARS) scientists from the Australian Biological Control Laboratory assisted in solving the problem by releasing biological controls in the form of insects that feed on Melaleuca. These insects are natural predators of Melaleuca in Australia and help control the spread of the weed in the U.S.

Traditional Aboriginal uses
Australian Aborigines used the leaves traditionally for many medicinal purposes, including chewing the young leaves to alleviate headache and for other ailments.
The softness and flexibility of the paperbark itself made it an extremely useful tree to aboriginal people. It was used to line coolamons when used as cradles, as a bandage, as a sleeping mat, and as material for building humpies. It was also used for wrapping food for cooking (in the same way aluminium foil is today), as a disposable raincoat, and for tamping holes in canoes. In the Gadigal language, it is called Bujor
Modern Uses:
Scientific studies have shown that tea tree oil made from Melaleuca alternifolia is a highly effective topical antibacterial and antifungal, although it may be toxic when ingested internally in large doses or by children. In rare cases, topical products can be absorbed by the skin and result in toxicity.
The oils of Melaleuca can be found in organic solutions of medication that claims to eliminate warts, including the Human papillomavirus. No scientific evidence proves this claim (reference: “Forces of Nature: Warts No More”).
Melaleuca oils are the active ingredient in Burn-Aid, a popular minor burn first aid treatment (an offshoot of the brandname Band-Aid).
Melaleuca oils (tea tree oil) is also used in many pet fish remedies (such as Melafix and Bettafix) to treat bacterial and fungal infections.[citation needed] Bettafix is a lighter dilution of tea tree oil while Melafix is a stronger dilution. It is most commonly used to promote fin and tissue regrowth. The remedies are often associated with Betta fish (Siamese Fighting Fish) but are also used with other fish.
It is the primary species for commercial production of Tea tree oil (melaleuca oil), a topical antibacterial and antifungal used in a range of products including antiseptics, deodorants, shampoos, soaps and lotions.
The essential oil is distilled from the feathery, narrow bright green leaves. Tea tree’s major contribution to the herbal pharmacy is its broad spectrum of antimicrobial activity. Often called a “first aid kit in a bottle”, it is ideal to take along on camping trip or anytime you are traveling. Tea tree is also an all purpose remedy for respiratory infections, acting as an anti-infective agent and strongly stimulating the body’s own.

Habitat : E. Asia – E. China, S. Japan, Korea, Manchuria Moist places in meadows in lowlands, near rivers and on wooded hillsides. Grassy slopes and hillsides from near sea level to 1700 metres in China.
Description:
Bulb growing to 0.15m at a slow rate.
It is hardy to zone 7 and is not frost tender. It is in flower from March to April, and the seeds ripen from May to June. The flowers are hermaphrodite (have both male and female organs).
The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil.
Cultivation
Easily grown in a well-drained soil in a sunny position[1, 90]. This species is not fully hardy in Britain, the plants come into growth in the winter and need protection from severe weather and so are best grown in a bulb frame[1]. Plants are dormant in summer but do not require protection from rain[90]. Bulbs can be harvested in June after they have died down and then stored in a cool dry place, being planted out again in October.
Propagation
Seed – best sown in a shady part of the cold frame as soon as it is ripe in early summer, or in the early autumn. A spring sowing of stored seed in the greenhouse also succeeds. Sow the seed thinly so that the seedlings can be grown on without disturbance for their first growing season – apply liquid feeds to the pot if necessary. Divide the bulbs once the plants have become dormant, putting 3 – 4 bulbs in each pot. Grow the on in the greenhouse for at least the next year, planting them out when dormant. Division of offsets in July. Larger bulbs can be planted out straight into their permanent positions, or can be stored in a cool place and then be planted out in late autumn. It is best to pot up smaller bulbs and grow them on in a cold frame for a year before planting them out when they are dormant in late summer to the middle of autumn.
Edible Uses
Edible Parts: Leaves; Root.
Bulb – cooked. A source of starch. The bulb can be up to 4cm in diameter. Leaves – cooked. Unless you have more plants than you need this practise is not recommended since it will greatly weaken the plant.
The inner portion of the bulb is antidote, antipyretic, depurative, expectorant, febrifuge and laxative. It is used, mainly as a poultice, in the treatment of ulcers and abscesses. The plant has been used in the treatment of cancer. The leaves are applied externally to abscesses, buboes and breast diseases. The flowers are used in the treatment of dysuria.
Known Hazards: Although no records of toxicity have been seen for this species, the bulbs and the flowers of at least one member of this genus have been known to cause dermatitis in sensitive people, though up to 5 bulbs a day of that species can be eaten without ill-effect.

Defenition: Autism is a brain development disorder that impairs social interaction and communication, and causes restricted and repetitive behavior, all starting before a child is three years old. This set of signs distinguishes autism from milder autism spectrum disorders (ASD) such as Asperger syndrome.
Most infants and young children are very social creatures who need and want contact with others to thrive and grow. They smile, cuddle, laugh, and respond eagerly to games like “peek-a-boo” or hide-and-seek. Occasionally, however, a child does not interact in this expected manner. Instead, the child seems to exist in his or her own world, a place characterized by repetitive routines, odd and peculiar behaviors, problems in communication, and a lack of social awareness or interest in others. These are characteristics of a developmental disorder called autism……….CLICK & SEE
Autism has a strong genetic basis, although the genetics of autism are complex and it is unclear whether ASD is explained more by multigene interactions or by rare mutations. In rare cases, autism is strongly associated with agents that cause birth defects. Other proposed causes, such as childhood vaccines, are controversial and the vaccine hypotheses lack convincing scientific evidence. Most recent reviews estimate a prevalence of one to two cases per 1,000 people for autism, and about six per 1,000 for ASD, with ASD averaging a 4.3:1 male-to-female ratio. The number of people known to have autism has increased dramatically since the 1980s, at least partly due to changes in diagnostic practice; the question of whether actual prevalence has increased is unresolved.
Autism affects many parts of the brain; how this occurs is poorly understood. Parents usually notice signs in the first two years of their child’s life. Early behavioral or cognitive intervention can help children gain self-care, social, and communication skills. There is no cure. Few children with autism live independently after reaching adulthood, but some become successful, and an autistic culture has developed, with some seeking a cure and others believing that autism is a condition rather than a disorder.
Characteristics : Autism is distinguished by a pattern of symptoms rather than one single symptom. The main characteristics are impairments in social interaction, impairments in communication, restricted interests and repetitive behavior. Other aspects, such as atypical eating, are also common but are not essential for diagnosis. Individual symptoms of autism occur in the general population and appear not to associate highly, without a sharp line separating pathological severity from common traits.
Symptoms:
Autism is usually identified by the time a child is three years of age. It is often discovered when parents become concerned that their child may be deaf, is not yet talking, resists cuddling, and avoids interactions with others.
A preschool age child with “classic” autism is generally withdrawn, aloof, and fails to respond to other people. Many of these children will not even make eye contact. They may also engage in odd or ritualistic behaviors like rocking, hand flapping, or an obsessive need to maintain order.
Many children with autism do not speak at all. Those who do may speak in rhyme, have echolalia (repeating a person’s words like an echo), refer to themselves as “he” or “she”, or use peculiar language.
The severity of autism varies widely, from mild to severe. With proper supports, many of these children are able to perform well in a school setting and may be able to live independently when they grow up. Other children with autism function at a much lower level. Mental retardation is commonly associated with autism. Occasionally, a child with autism may display an extraordinary talent in art, music, or another specific area.
Autistic individuals display many forms of repetitive or restricted behavior, which the Repetitive Behavior Scale-Revised (RBS-R) categorizes as follows.
* Stereotypy is apparently purposeless movement, such as hand flapping, head rolling, or body rocking.
* Compulsive behavior is intended and appears to follow rules, such as arranging objects in a certain way.
* Sameness is resistance to change; for example, insisting that the furniture not be moved or refusing to be interrupted.
* Ritualistic behavior involves the performance of daily activities the same way each time, such as an unvarying menu or dressing ritual. This is closely associated with sameness and an independent validation has suggested combining the two factors.
* Restricted behavior is limited in focus, interest, or activity, such as preoccupation with a single television program.
* Self-injury includes movements that injure or can injure the person, such as biting oneself. Dominick et al. reported that self-injury at some point affected about 30% of children with ASD.
No single repetitive behavior seems to be specific to autism, but only autism appears to have an elevated pattern of occurrence and severity of these behaviors.
* Lack of pointing to direct others’ attention to objects (occurs in the first 14 months of life)
* Does not adjust gaze to look at objects that others are looking at
* Cannot start or sustain a social conversation
* Develops language slowly or not at all
* Repeats words or memorized passages, such as commercials
* Does not refer to self correctly (for example, says “you want water” when the child means “I want water”)
* Uses nonsense rhyming
* Communicates with gestures instead of words
* Shows a lack of empathy
* Does not make friends
* Is withdrawn
* Prefers to spend time alone, rather than with others
* May not respond to eye contact or smiles
* May actually avoid eye contact
* May treat others as if they are objects
* Does not play interactive games
Response to sensory information:
* Has heightened or low senses of sight, hearing, touch, smell, or taste
* Seems to have a heightened or low response to pain
* May withdraw from physical contact because it is overstimulating or overwhelming
* Does not startle at loud noises
* May find normal noises painful and hold hands over ears
* Rubs surfaces, mouths or licks objects
Play:
* Shows little pretend or imaginative play
* Doesn’t imitate the actions of others
* Prefers solitary or ritualistic play
Behaviors:
* Has a short attention span
* Uses repetitive body movements
* Shows a strong need for sameness
* “Acts up” with intense tantrums
* Has very narrow interests
* Demonstrates perseveration (gets stuck on a single topic or task)
* Shows aggression to others or self
* Is overactive or very passive
Causes:
The cause of autism remains unknown, although current theories indicate a problem with function or structure of the central nervous system. What we do know, however, is that parents or “inadequate parenting” do not cause autism.
Genetic factors seem to be important. For example, identical twins are much more likely than fraternal twins or siblings to both have autism. Similarly, language abnormalities are more common in relatives of autistic children. Chromosomal abnormalities and other neurological problems are also more common in families with autism.
A number of other possible causes have been suspected, but not proven. They involve digestive tract changes, diet, mercury poisoning, vaccine sensitivity, and the body’s inefficient use of vitamins and minerals.
The exact number of children with autism is not known. A report released by the U.S. Centers for Disease Control and Prevention (CDC) suggests that autism and related disorders are more common than previously thought, although it is unclear if this is due to an increasing rate of the illness or an increased ability to diagnose the illness.
Autism affects boys 3 to 4 times more often than girls. Family income, education, and lifestyle do not seem to affect the risk of autism.
Some parents have heard that the MMR vaccine that children receive may cause autism. This theory was based, in part, on two facts. First, the incidence of autism has increased steadily since around the same time the MMR vaccine was introduced. Second, children with the regressive form of autism (a type of autism that develops after a period of normal development) tend to start to show symptoms around the time the MMR vaccine is given. This is likely a coincidence due to the age of children at the time they receive this vaccine.
Several major studies have found NO connection between the vaccine and autism, however. The American Academy of Pediatrics and the Center for Disease Control and Prevention report that there is no proven link between autism and the MMR vaccine.
Some doctors attribute the increased incidence in autism to newer definitions of autism. The term “autism” now includes a wider spectrum of children. For example, a child who is diagnosed with high-functioning autism today may have been thought to simply be odd or strange 30 years ago.
Screening & Diagnosis:
:All children should have routine developmental exams by their pediatrician. Further testing may be needed if there is concern on the part of the clinician or the parents. This is particularly true whenever a child fails to meet any of the following language milestones:
* Babbling by 12 months
* Gesturing (pointing, waving bye-bye) by 12 months
* Single words by 16 months
* Two-word spontaneous phrases by 24 months (not just echoing)
* Loss of any language or social skills at any age.
These children might receive a hearing evaluation, a blood lead test, and a screening test for autism (such as the Checklist for Autism in Toddlers (CHAT) or the Autism Screening Questionnaire).
A health care provider experienced in the diagnosis and treatment of autism is usually necessary for the actual diagnosis. Because there is no biological test for autism, the diagnosis will often be based on very specific criteria laid out in a book called the Diagnostic and Statistical Manual IV.
The other pervasive developmental disorders include:
* Asperger syndrome (like autism, but with normal language development)
* Rett syndrome (very different from autism, and only occurs in females)
* Childhood disintegrative disorder (rare condition where a child acquires skills, then loses them by age 10)
* Pervasive developmental disorder – not otherwise specified (PDD-NOS), also called atypical autism.
An evaluation of autism will often include a complete physical and neurologic examination. It may also include a specific diagnostic screening tool, such as:
Children with known or suspected autism will often have genetic testing (looking for chromosome abnormalities) and perhaps metabolic testing.
Autism encompasses a broad spectrum of symptoms. Therefore, a single, brief evaluation cannot predict a child’s true abilities. Ideally, a team of different specialists will evaluate the child. They might evaluate speech, language, communication, thinking abilities, motor skills, success at school, and other factors.
Underdiagnosis and overdiagnosis are problems in marginal cases, and much of the recent increase in the number of reported ASD cases is likely due to changes in diagnostic practices. The increasing popularity of drug treatment options and the expansion of benefits has given providers incentives to diagnose ASD, resulting in some overdiagnosis of children with uncertain symptoms. Conversely, the cost of screening and diagnosis and the challenge of obtaining payment can inhibit or delay diagnosis. It is particularly hard to diagnose autism among the visually impaired, partly because some of its diagnostic criteria depend on vision, and partly because autistic symptoms overlap with those of common blindness syndromes.
The symptoms of autism and ASD begin early in childhood but are occasionally missed. Adults may seek retrospective diagnoses to help them or their friends and family understand themselves, to help their employers make adjustments, or in some locations to claim disability living allowances or other benefits.
Sometimes people are reluctant to have a child diagnosed because of concerns about labeling the child. However, failure to make a diagnosis can lead to failure to get the treatment and services the child needs.
Treatment
An early, intensive, appropriate treatment program will greatly improve the outlook for most young children with autism. Most programs will build on the interests of the child in a highly structured schedule of constructive activities. Visual aids are often helpful.
Treatment is most successful when geared toward the child’s particular needs. An experienced specialist or team should design the individualized program. A variety of effective therapies are available, including applied behavior analysis (ABA), speech-language therapy, medications, occupational therapy, and physical therapy. Sensory integration and vision therapy are also common, but there is little research supporting their effectiveness. The best treatment plan may use a combination of techniques.
APPLIED BEHAVIORAL ANALYSIS (ABA)
This program is for younger children with an autism spectrum disorder. It highly effective in many cases. ABA uses a one-on-one teaching approach that relies on reinforced practice of various skills. The goal is to get the child close to typical developmental functioning.
ABA programs are usually conducted within a child’s home, under the supervision of a behavioral psychologist. Unfortunately, these programs can be very expensive and have not been widely adopted by school systems. Parents often must seek funding and staffing from other sources, which can be hard to find in many communities.
TEACCH
Another program is called the Treatment and Education of Autistic and Related Communication Handicapped Children (TEACCH). TEACCH, developed as a statewide program in North Carolina, uses picture schedules and other visual cues. These help the child work independently and to organize and structure their environments. Though TEACCH tries to enhance a child’s adaptation and skills, there is also an acceptance of the deficits associated with autism spectrum disorders. In contrast to ABA programs, TEACCH programs do not anticipate that children will achieve typical developmental progress in response to the treatment.
MEDICINE
Medicines are often used to treat behavior or emotional problems that people with autism may have. These include hyperactivity, impulsiveness, attention problems, irritability, mood swings, outbursts, tantrums, aggression, extreme compulsions that the child finds it impossible to suppress, sleep difficulty, and anxiety. Currently, only risperidone is approved for treatment of children ages 5-16 with irritability and aggression associated with autism.
DIET
Some children with autism appear to respond to a gluten-free or a casein-free diet. Gluten is found in foods containing wheat, rye, and barley. Casein is found in milk, cheese, and other dairy products. Not all experts agree that dietary changes will make a difference, and not all reports studying this method have shown positive results.
If considering these or other dietary changes, seek guidance from both a gastroenterologist (doctor who specializes in the digestive system) and a registered dietitian. You want to be sure that the child is still receiving adequate calories, nutrients, and a balanced diet.
OTHER APPROACHES
Beware that there are widely publicized treatments for autism that do not have scientific support, and reports of “miracle cures” that do not live up to expectations. If your child has autism, it may be helpful to talk with other parents of children with autism, talk with autism specialists, and follow the progress of research in this area, which is rapidly developing.
At one time, there was enormous excitement about using secretin infusions. Now, after many studies have been conducted in many laboratories, it’s possible that secretin is not effective after all, but research is ongoing.
Support Groups
For organizations that can provide additional information and help on autism, see autism resources.
Prognosis:
There is no cure. Children recover occasionally, sometimes after intensive treatment and sometimes not; it is not known how often this happens. Most children with autism lack social support, meaningful relationships, future employment opportunities or self-determination. Although core difficulties remain, symptoms often become less severe in later childhood. Few high-quality studies address long-term prognosis. Some adults show modest improvement in communication skills, but a few decline; no study has focused on autism after midlife. Acquiring language before age six, having IQ above 50, and having a marketable skill all predict better outcomes; independent living is unlikely with severe autism. A 2004 British study of 68 adults who were diagnosed before 1980 as autistic children with IQ above 50 found that 12% achieved a high level of independence as adults, 10% had some friends and were generally in work but required some support, 19% had some independence but were generally living at home and needed considerable support and supervision in daily living, 46% needed specialist residential provision from facilities specializing in ASD with a high level of support and very limited autonomy, and 12% needed high-level hospital care. A 2005 Swedish study of 78 adults that did not exclude low IQ found worse prognosis; for example, only 4% achieved independence. A 2008 Canadian study of 48 young adults diagnosed with ASD as preschoolers found outcomes ranging through poor (46%), fair (32%), good (17%), and very good (4%); only 56% had ever been employed, most in volunteer, sheltered or part time work. Changes in diagnostic practice and increased availability of effective early intervention make it unclear whether these findings can be generalized to recently diagnosed children.

The leaves and flowers of A Africana, a bristle-covered herb known as the “hemorrhage plant,” have been used to stanch bleeding, remove foreign bodies from the eyes, treat scorpion stings, and for several other purposes across the African continent, note Dr Charles O Okoli and colleagues at the University of Nigeria.
To test the plant’s medicinal properties, Okoli and his team performed a series of lab and animal experiments comparing the effects of an extract of the powdered leaves in methanol, and two different portions or fractions containing hexane or methanol. They report their findings in BMC Complementary and Alternative Medicine.
The extract and the fractions of the plant significantly reduced bleeding and clotting time in rats, the researchers found, with the methanol fraction having the strongest effect.
