Habitat : Viburnum nudum is native to Eastern N. America – Maryland to Florida, west to Arkansas and Kentucky. It grows on wooded swamps, wet pinelands and bogs. Also found on rich hillsides.
Viburnum nudum is a medium large deciduous shrub growing from 5-l5’ tall and half as wide. The egg-shaped leaves are smooth, lustrous dark green from 2-4” long and about half as wide. The margins can be entire or wavy edged but rarely toothed. The creamy white flowers which appear in late April in the Atlanta area are individually small but are grouped in large fertile flat head clusters that emerge after the foliage has expanded. The fruit which forms in late summer and early fall emerges light greenish yellow, progressives to pink or red before it turns to a glaucus deep blue at maturity.. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is not self-fertile....CLICK & SEE THE PICTURES
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very acid soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
An easily grown plant, it succeeds in most soils but is ill-adapted for poor soils and for dry situations. It prefers a deep rich loamy soil in sun or semi-shade. Best if given shade from the early morning sun in spring. Plants often grow in quite acid soils in the wild. Plants are self-incompatible and need to grow close to a genetically distinct plant in the same species in order to produce fruit and fertile seed. This species is closely related to V. cassinoides. Special Features: Attracts birds, North American native, Wetlands plant, Fragrant flowers, Attractive flowers or blooms. Propagation:
Seed – best sown in a cold frame as soon as it is ripe. Germination can be slow, sometimes taking more than 18 months. If the seed is harvested ‘green’ (when it has fully developed but before it has fully ripened) and sown immediately in a cold frame, it should germinate in the spring. Stored seed will require 2 months warm then 3 months cold stratification and can still take 18 months to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a cold frame or greenhouse. Plant out into their permanent positions in late spring or early summer of the following year. Cuttings of soft-wood, early summer in a frame. Pot up into individual pots once they start to root and plant them out in late spring or early summer of the following year. Cuttings of half-ripe wood, 5 – 8 cm long with a heel if possible, July/August in a frame. Plant them into individual pots as soon as they start to root. These cuttings can be difficult to overwinter, it is best to keep them in a greenhouse or cold frame until the following spring before planting them out. Cuttings of mature wood, winter in a frame. They should root in early spring – pot them up when large enough to handle and plant them out in the summer if sufficient new growth is made, otherwise keep them in a cold frame for the next winter and then plant them out in the spring. Layering of current seasons growth in July/August. Takes 15 months. Edible Uses: Fruit –raw or cooked. It usually has a sweetish flavour but is sometimes bitter and is usually unpalatable. The ovoid fruit is about 8mm long and contains a single large seed.
Antispasmodic; Diuretic; Tonic.
A tea made from the bark is antispasmodic, diuretic, tonic and uterine sedative
Other Uses: Landscape Uses:Screen, Specimen. Garden use: The size of Viburnum nudum makes it a perfect choice for all but the smallest of gardens. Even in a tiny garden it could be used as a small tree. Its upright habit and branch structure makes it agreeable for ‘treeing up’ to show off its attractive smooth, tan bark. Use it in groups in a shrub border or in a wet area. Because it will tolerate full sun or light shade, it makes a good transitional shrub when going from sunny areas to shady areas. Used in this way it combines well with wax myrtles, Agarista, and other Viburnum species. For a sunny exposure a stunning combination would be planting it with winter honeysuckle (Lonicera fragantissima) and ‘Crimson Pigmy’ Barberry. Add a chinese Loropetalum and this area could be a study in contrast of texture and color.

Common names : Bisnaga, Toothpickweed, and Khella.
Habitat: Ammi visnaga is native to Europe, Asia, and North Africa, but it can be found throughout the world as an introduced species.It grows in fields and sandy places. Description:
Ammi visnaga is an annual or biennial herb growing from a taproot erect to a maximum height near 80 centimeters. Leaves are up to 20 centimeters long and generally oval to triangular in shape but dissected into many small linear to lance-shaped segments. The inflorescence is a compound umbel of white flowers similar to those of other Apiaceae species. The fruit is a compressed oval-shaped body less than 3 millimeters long. This and other Ammi species are sources of khellin, a diuretic extract.
It is in flower from Jul to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is self-fertile.
Prefers a well-drained soil in a sunny position, succeeding in ordinary garden soil. Tolerates a pH in the range 6.8 to 8.3. This species is not fully winter-hardy in the colder areas of Britain, though it should be possible to grow it as a spring-sown annual. This plant is sold as toothpicks in Egyptian markets.
Propagation: Seed – sow spring in situ. ( Sow under cover Feb-March in a seed tray, module or guttering. Sow direct March-May and/or August-September.) Edible Uses: Leaves are chewed raw for their pleasant aromatic flavour
Khellin, a chemical obtained from Ammi visnaga gives rose red color with KOH (solid) or NaOH & 2-3 drops of water, was used at one time as a smooth muscle relaxant, but its use is limited due to adverse side effects. Amiodarone and cromoglycate are derivates of khellin that are frequently used in modern medicine.
The chemical visnagin, which is found in A. visnaga, has biological activity in animal models as a vasodilator and reduces blood pressure by inhibiting calcium influx into the cell. Medicinal Uses:
Antiarrhythmic; Antiasthmatic; Antispasmodic; Diuretic; Lithontripic; Vasodilator.
Visnaga is an effective muscle relaxant and has been used for centuries to alleviate the excruciating pain of kidney stones. Modern research has confirmed the validity of this traditional use. Visnagin contains khellin, from which particularly safe pharmaceutical drugs for the treatment of asthma have been made. The seeds are diuretic and lithontripic. They contain a fatty oil that includes the substance ‘khellin’. This has been shown to be of benefit in the treatment of asthma. Taken internally, the seeds have a strongly antispasmodic action on the smaller bronchial muscles, they also dilate the bronchial, urinary and blood vessels without affecting blood pressure. The affect last for about 6 hours and the plant has practically no side effects. The seeds are used in the treatment of asthma, angina, coronary arteriosclerosis and kidney stones. By relaxing the muscles of the urethra, visnaga reduces the pain caused by trapped kidney stones and helps ease the stone down into the bladder. The seeds are harvested in late summer before they have fully ripened and are dried for later use.
In Egypt, a tea made from the fruit of this species has been used as an herbal remedy for kidney stones. Laborarory rat studies show that the extract slows the buildup of calcium oxalate crystals in the kidneys and acts as a diuretic.
This plant and its components have shown effects in dilating the coronary arteries. Its mechanism of action may be very similar to the calcium channel-blocking drugs. The New England Journal of Medicine writes “The high proportion of favorable results, together with the striking degree of improvement frequently observed, has led us to the conclusion that Khellin, properly used, is a safe and effective drug for the treatment of angina pectoris.” As little as 30 milligrams of Khellin per day appear to offer as good a result, with fewer side effects. Rather than use the isolated compound “Khellin,” Khella extracts standardized for khellin content (typically 12 percent) are the preferred form.
A daily dose of such an extract would be 250 to 300 milligrams. Khella appears to work very well with hawthorn extracts. An aromatic herb which dilates the bronchial, urinary and blood vessels without affecting blood pressure.
Visnaga is a traditional Egyptian remedy for kidney stones. By relaxing the muscles of the ureter, visnaga reduces the pain caused by the trapped stone and helps ease the stone down into the bladder. Following research into its antispasmodic properties, visnaga is now given for asthma and is safe even for children to take. Although it does not always relieve acute asthma attacks, it do3es help to prevent their recurrence. It is an effective remedy for various respiratory problems, including bronchitis, emphysema, and whooping cough. In Andalusia in Spain, the largest and best quality visnaga were employed to clean the teeth. Khella is the source of amiodarone one of the key anti-arrhythmia medications. The usual recommendation calls for pouring boiling water over about a quarter-teaspoon of powdered khella fruits. Steep for five minutes and drink the tea after straining.
Its active constituent is khellin, a bronchiodilator and antispasmodic that makes it useful for asthma sufferers It’s best used to prevent asthma rather than to counter an attack and can be taken on a daily basis with no contraindications. Because khella builds up in the blood, its use can be decreased after a period of time. Khella is safer than ma huang (ephedra) for asthma sufferers because it’s nonstimulating and nonenervating. Unlike ma huang, it doesn’t rob the body, especially the adrenals, of energy.
Spasmolytic action of khellin and visnagin (both furanochromones) is indicated for treatment of asthma and coronary arteriosclerosis.
An extract from khella (Ammi visnaga) is so far the only herb found to be useful in vitili. Khellin, the active constituent, appears to work like psoralen drugs?it stimulates repigmentation of the skin by increasing sensitivity of remaining pigment-containing cells (melanocytes) to sunlight. Studies have used 120-160 mg of khellin per day. Khellin must be used with caution, as it can cause side effects such as nausea and insomnia.
Another use is for vitiligo (an extract from ammi visnaga appears to stimulate repigmentation of the skin by increasing sensitivity of remaining pigment containing cells, melanocytes to sunlight)
Other Uses: The fruiting pedicel is used as a toothpick whilst the seeds have been used as a tooth cleaner
Known Hazards : Skin contact with the sap is said to cause photo-sensitivity and/or dermatitis in some people. Avoid during pregnancy and lactation. Avoid if on warfarin or other blood thinning medication. Prolonged use may lead to: constipation, appetite loss, headaches, vertigo, nausea and vomiting.

Water makes up around 75 per cent of the human body. It’s important for digestion, joint function, healthy skin and removal of waste products. CLICK & SEE
Dehydration occurs when more fluid is lost from the body than is taken in. This causes an imbalance in important minerals, such as sodium and potassium, which are required for muscle and nerve function.
If there is a one per cent or greater loss in body weight because of fluid loss, dehydration occurs. This may be mild, moderate or severe, depending on the amount lost.
Infants and children are more susceptible to dehydration than adults because of their smaller body weights and higher turnover of water and electrolytes. The elderly and those with illnesses are also at higher risk.
Dehydration is classified as mild, moderate, or severe based on how much of the body’s fluid is lost or not replenished. When severe, dehydration is a life-threatening emergency.
Who are at Risk? Anyone’s at risk of dehydration, but some people are more at risk than others.
•Babies and young children have relatively low body weights, making them more vulnerable to the effects of fluid loss. •Older adults tend to eat less and may forget to eat and drink during the day. With increasing age, the body’s ability to conserve water decreases and a person’s sense of thirst becomes less acute. Illness and disability are also more common, which may make it harder to eat and drink enough. •People with long-term medical conditions, such as kidney disease and alcoholism, are more at risk of dehydration. •Short-term, acute health problems, such as viral infections, can result in dehydration because fever and increased sweating mean more fluid is lost from the body. Such illnesses may also make you feel less inclined to eat and drink. •People living or working in hot climates or those who take part in sports or other strenuous physical activities are at greater risk of dehydration.
The body’s initial responses to dehydration are thirst to increase water intake along with decreased urine output to try to conserve water. The urine will become concentrated and more yellow in color.
As the level of water loss increases, more symptoms can become apparent. The following are further signs and symptoms of dehydration:
•the eyes stop making tears,
•sweating may stop,
•nausea and vomiting,
•heart palpitations, and
•lightheadedness (especially when standing).
The body tries to maintain cardiac output (the amount of blood that is pumped by the heart to the body); and if the amount of fluid in the intravascular space is decreased, the body tries to compensate for this decrease by increasing the heart rate and making blood vessels constrict to try to maintain blood pressure and blood flow to the vital organs of the body. This coping mechanism begins to fail as the level of dehydration increases.
With severe dehydration, confusion and weakness will occur as the brain and other body organs receive less blood. Finally, coma and organ failure, and death eventually will occur if the dehydration remains untreated.
Around two-thirds of the water we need comes from drinks. Up to one-third comes from food (tomatoes, cucumber, fish and poultry are good sources). Some is also provided as a result of chemical reactions within the body. CLICK & SEE
The average adult loses around 2.5 litres of water every day through the normal processes of breathing, sweating and waste removal. If we lose more fluid than usual this tips the balance towards dehydration.
Your body may lose too much fluids from:
•Vomiting or diarrhea
•Excessive urine output, such as with uncontrolled diabetes or diuretic use
•Excessive sweating (for example, from exercise)
You might not drink enough fluids because of:
•Loss of appetite due to illness
•Sore throat or mouth sores
Dehydration in sick children is often a combination of both — refusing to eat or drink anything while also losing fluid from vomiting, diarrhea, or fever.
Lifestyle factors such as drinking too much alcohol, exercise, being in a hot environment or being too busy to drink liquid can also lead to dehydration.
Dehydration is often a clinical diagnosis. Aside from diagnosing the reason for dehydration, the health care practitioner’s examination of the patient will assess the level of dehydration. Initial evaluations may include:
•Mental status tests to evaluate whether the patient is awake, alert, and oriented. Infants and children may appear listless and have whiny cries and decreased muscle tone.
•Vital signs may include postural readings (blood pressure and pulse rate are taken lying down and standing). With dehydration, the pulse rate may increase and the blood pressure may drop because the intravascular space is depleted of fluid. People taking beta blocker medications for high blood pressure, heart disease, or other indications, occasionally lose the ability to increase their heart rate as a compensation mechanism since these medications block the adrenaline receptors in the body.
•Temperature may be measured to assess fever.
•Skin may be checked to see if sweat is present and to assess the degree of elasticity (turgor). As dehydration progresses, the skin loses its water content and becomes less elastic.
•Infants may have additional evaluations performed, including checking for a soft spot on the skull (sunken fontanelle), assessing the suck mechanism, muscle tone, or loss of sweat in the armpits and groin. All are signs of potential significant dehydration.
•Pediatric patients are often weighed during routine child visits, thus a body weight measurement may be helpful in assessing how much water has been lost with the acute illness.
The purpose of blood tests is to assess potential electrolyte abnormalities (especially sodium levels) associated with the dehydration. Tests may or may not be done on the patient depending upon the underlying cause of dehydration, the severity of illness, and the health care practitioner’s assessment of their needs.
Urinalysis may be done to determine urine concentration – the more concentrated the urine, the more dehydrated the patient.
As is often the case in medicine, prevention is the important first step in the treatment of dehydration. (Please see the home treatment and prevention sections.)
Fluid replacement is the treatment for dehydration. This may be attempted by replacing fluid by mouth, but if this fails, intravenous fluid (IV) may be required. Should oral rehydration be attempted, frequent small amounts of clear fluids should be used.
Clear fluids include:
•other replacement fluids that may contain electrolytes (Pedialyte, Gatorade, Powerade, etc.)
Decisions about the use of intravenous fluids depend upon the health care practitioner’s assessment of the extent of dehydration and the ability for the patient to recover from the underlying cause.
The success of the rehydration therapy can be monitored by urine output. When the body is dry, the kidneys try to hold on to as much fluid as possible, urine output is decreased, and the urine itself is concentrated. As treatment occurs, the kidneys sense the increased amount of fluid, and urine output increases.
Medications may be used to treat underlying illnesses and to control fever, vomiting, or diarrhea.
Home Treatment: Dehydration occurs over time. If it can be recognized in its earliest stages, and if its cause can be addressed, home treatment may be beneficial and adequate.
Steps a person can take at home to prevent severe dehydration include:–
•Individuals with vomiting and diarrhea can try to alter their diet and use medications to control symptoms to minimize water loss. Clear fluids often recommended as the diet of choice for the first 24 hours, with gradual progression to a BRAT diet (bananas, rice, apples, toast) and then adding more foods as tolerated.
•Loperamide (Imodium) may be considered to control diarrhea.
•Acetaminophen or ibuprofen may be used to control fever.
•Fluid replacements may be attempted by small, frequent amounts of clear fluids (see clear fluids information in previous section). The amount of fluid required to maintain hydration depends upon the individual’s weight. The average adult needs between 2 and 3 liters of fluid per day.
If the person becomes confused or lethargic; if there is persistent, uncontrolled fever, vomiting, or diarrhea; or if there are any other specific concerns, then medical care should be accessed.
Prevention:- •Environment: Dehydration due to the weather is a preventable condition. If possible, activities should not be scheduled in the heat of the day. If they are, adequate fluids should be available, and cooler, shaded areas should be used if possible. Of course, people should be monitored to make certain they are safe. Those working in hot environments need to take care to rehydrate often. •Exercise: People exercising in a hot environment need to drink adequate amounts of water. •Age: The young and elderly are most at risk. During heat waves, attempts should be made to check on the elderly in their homes. During the Chicago heat wave of 1995, more than 600 people died in their homes from heat exposure. •Heat related conditions: Know the signs and symptoms of heat cramps, heat rash, heat exhaustion, and heat stroke. Preventing dehydration is one step to avoid these conditions.
Carefully monitor someone who is ill, especially an infant, child, or older adult. If you believe that dehydration is developing, consult a doctor before the person becomes moderately or severely dehydrated. Begin fluid replacement as soon as vomiting and diarrhea start — DO NOT wait for signs of dehydration.
Always encourage the person to drink during an illness, and remember that a person’s fluid needs are greater when that person has fever, vomiting, or diarrhea. The easiest signs to monitor are urine output (there should be frequent wet diapers or trips to the bathroom), saliva in the mouth, and tears when crying.

While manganese is naturally occurring in soil and groundwater around the world, some of Canada’s groundwater contains an unusually high amount of it, giving the researchers an opportunity to study whether excessive manganese can adversely affect human health.
“We found significant deficits in the intelligence quotient (IQ) of children exposed to higher concentration of manganese in drinking water,” said lead author Maryse Bouchard.
Yet, some areas where lower IQs were reported also registered concentrations below current guidelines. In response to the study, some of the affected municipalities have already decided to install special filtration systems.
