Can’t Find Sarcasm, It May be Dementia

Sarcasm may be the lowest form of wit, but Australian scientists are using it to diagnose dementia, according to research published.

Researchers at the University of New South Wales found that patients under the age of 65 suffering from frontotemporal dementia (FTD), the second most common form of dementia, cannot detect when someone is being sarcastic.

The study, described by its authors as groundbreaking, helps explain why patients with the condition behave the way they do and why, for example, they are unable to pick up their caregivers’ moods, the research showed.

“This is significant because if care-givers are angry, sad or depressed, the patient won’t pick this up. It is often very upsetting for family members,” said John Hodges, the senior author of the paper published in Brain.

“(FTD) patients present changes in personality and behaviour. They find it difficult to interact with people, they don’t pick up on social cues, they lack empathy, they make bad judgements,” he said. “People with FTD become very gullible and they often part with large amounts of money,” he said, adding that one in 4,000 people around the world are afflicted with the condition.

Researchers began studying the role of sarcasm in detecting FTD because it requires a patient to spot discrepancies between a person’s words and the tone of their voice, Hodges said.

“One of the things about FTD patients is that they don’t detect humour — they are very bad at double meaning and a lot of humour (other than sarcasm) is based on double meaning,” he said.

The research, conducted in 2006-07, put 26 sufferers of FTD and 19 Alzheimer’s patients through a test in which actors acted out different scenarios using exactly the same words. While in one scenario, the actors would deliver the lines sincerely, in others they would introduce a thick layer of sarcasm. Patients were then asked if they got the joke, Hodges said.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Coptis teeta is a rare species of flowering plant in the buttercup family. It is a species of importance in Chinese herbology. Known as Yunnan goldthread, its rhizome is used as an antimicrobial and anti-inflammatory. A number of factors contribute to its endangerment. It is endemic to a very small area in the eastern Himalayas where its habitat is rapidly declining, due in part to deforestation, it is overcollected for medicinal use, and its reproductive success is low. The plant is cultivated on a small scale in Yunnan using techniques that aim to conserve the species within its natural habitat. The Lisu people of the local area earn much of their income from cultivation of the plant, which they grow using traditional agroforestry methods that have little adverse impact on the ecosystem.

Cultivation details
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of this country. It is cultivated as a medicinal plant in China. The following notes are based on the general needs of the genus.

Succeeds in a light moist humus-rich slightly acidic soil with a northerly aspect or light shade.

Propagation
Seed – best sown in a greenhouse as soon as it is ripe in an ericaceous compost[164]. Seal the pot in a polythene bag until germination takes place, which is usually within 1 – 6 months at 10°c. Stored seed should be sown as early in the year as possible. Four weeks cold stratification may be beneficial. Prick out the seedlings into individual pots when they are large enough to handle and grow on in a shady part of the greenhouse for at least their first winter. Plant them out in mid-autumn or in spring.
The root is harvested in the autumn and can be used fresh or dried.


Medicinal Uses:

Alterative; Anaesthetic; Analgesic; Antibacterial; Antispasmodic; Febrifuge; Ophthalmic; Pectoral.

The root is a pungent, very bitter, cooling herb that controls bacterial and viral infections, relaxes spasms, lowers fevers and stimulates the circulation. It is locally analgesic and anaesthetic and is used in Chinese medicine as a general panacea with alterative, ophthalmic and pectoral activity. The root contains several compounds that are effective in inhibiting various bacteria and they are a safe and effective treatment for many ailments, such as some forms of dysentery, that are caused by bacteria.

Improves appetite, restores digestion, gas, visceral obstructions, jaundice,improves bile flow, chronic gall bladder inflammation, debility, convalescence after fevers, debilitating diseases, atonic indigestion, mild forms of intermittent fevers, catarrhal and rheumatic conjunctivitis, dries excessive body moisture (e.g., water retention), all Pitta disorders, anal fissure, ulcerative colitis, vaginal infections, tumors, boils, carbuncles, inflammatory skin conditions, externally applied to sores (including mouth sores).

Alternative Medicine is Way Cool, Mom

[amazon_link asins=’1932073205,B008QSLL38,B01N57UTG4,B01N1U4QL8,B01M5IK07E,B01BQW262A,B00N594LKI,B01N8VC0IC,B000703AQ4′ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’fe314a7f-479d-11e7-bb24-ada56f69b796′]

Roughly 2.8 million children use herbal remedies, a study suggests. Adults play a key role: Kids are five times more likely to use nontraditional therapies if a parent or other relative did……….CLICK & SEE

Reporting from Atlanta — Just like their parents, kids are taking herbal supplements including fish oil and ginseng, a sign of just how mainstream alternative medicine has become.

More than 1 in 9 children and teens try those remedies and other nontraditional options, the government said Wednesday in its first national study of young people’s use of these mostly unproven treatments.

Given that children are generally healthy, the finding that so many of them use alternative medicine is “pretty amazing,” said one of the study’s authors, Richard Nahin of the National Center for Complementary and Alternative Medicine. The sweeping study suggests about 2.8 million young people use supplements.

Their parents’ practices played a big role. Kids were five times more likely to use alternative therapies if a parent or other relative did. The same study showed that more than a third of adults use alternative treatments, roughly the same as in a 2002 survey.

The researchers used a big umbrella in defining alternative medicine: Acupuncture, homeopathy, chiropractic care, traditional healing, yoga, Pilates, deep breathing, massage and even dieting were included.

Vitamin and mineral supplements are not considered alternative medicine, nor are prayer or folk medicine practices.

Herbal remedies were the leading type of alternative therapy for both adults and those younger than 18. Among children, such therapies were most often given for head or neck pain, colds and anxiety. Body aches and insomnia were other top reasons they were given alternative therapies, the study found.

Fish oil for hyperactivity and echinacea for colds were the most popular supplements, although there’s no proof such treatments work for those conditions, nor have they been tested in children.

Nahin cited the lack of rigorous scientific testing in declining to call such widespread use harmful or beneficial. Unlike federally regulated medicines, herbal remedies don’t have to be proven safe or effective to be sold. And studies that have been done on them have focused on adults, not children.

But some doctors are troubled that parents may be giving children alternative therapies in place of proven clinical treatments, said Dr. Wallace Sampson, an emeritus clinical professor of medicine at Stanford University.

“The reality is none of these things work, including some of the more popular ones. They’re placebos,” said Sampson, who was a founding editor of the Scientific Review of Alternative Medicine.

The study was done by the Centers for Disease Control and Prevention. It is based on a 2007 survey of more than 23,000 adults who were speaking about themselves and more than 9,000 who were speaking on behalf of a child in their household.

Medical doctors need to be careful about attacking alternative medicine because some long-endorsed pharmaceutical products have turned out to be treatment failures, noted Dr. Kathi Kemper, a pediatrician at the Wake Forest University School of Medicine.

For example, drug makers in October announced they no longer would recommend cough and cold medicines for children younger than 4, acknowledging there is scant evidence that they work in children and that in some cases, they might be dangerous.

“We have a pretty spotty history of being evidence-based ourselves,” said Kemper, who chairs an American Academy of Pediatrics committee on complementary and integrative medicine.

The cough medicine debacle is no rationale for embracing alternative medicine, said Dr. Seth Asser, who consults with a nonprofit organization opposed to faith healing and other religious practices used in lieu of conventional medicine.

“Two wrongs don’t make a right,” he said, adding that he believes there’s a “can’t beat ’em, join ’em” mentality toward alternative medicine among some doctors and hospital administrators.

There were some differences in how the 2002 and 2007 surveys were done. On the topic of herbal remedies, the 2007 study asked people whether they had used such a product in the previous 30 days, while the 2002 study asked if they had taken it in the last year.

That change may partly explain why adult use of some herbal remedies shifted significantly from 2002 to 2007. For example, echinacea use declined, but most people don’t suffer colds year-round. But news of the scientific failures of some remedies may also have an effect. A rigorous study in 2005 found that echinacea failed to prevent or treat colds.

Fish oil use was up. Some recent studies have suggested it can reduce heart disease risks, protect the eyes and provide other benefits.

“We think the public is listening to this data,” Nahin said.

Cinquefoil

[amazon_link asins=’B005CFF5AS,B006W32AHA,B00JXYHZ2U,B01N3QF1MM,B00JEMF59G,097201974X,B00DOODB8C,B01M13HLUY,B004HSDUXA’ template=’ProductCarousel’ store=’finmeacur-20′ marketplace=’US’ link_id=’ecd7b32a-0485-11e7-a4fc-6bd33d701e4f’]

Botanical Name:Potentilla simplex
Family: Rosaceae
Subfamily: Rosoideae
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Rosales
Genus: Potentilla
Common names:potentilla, five-fingers, tormentil, and barren strawberry.
Other Names: Five Fingers, Five-Finger Blossom, Five-finger grass, Sunkfield, Synkefoyle, Common Cinquefoil, Creeping Cinquefoil, Oldfield Cinquefoil
Parts used: The whole plant flowering, leaves.

Habitat:
Native to Eastern and Central N. America from Nova Scotia to North Carolina, Alabama, Minnesota and Missouri. Found growing in dry open woods, prairie hillsides, roadsides, old fields and waste places.

Description:
Cinquefoil is a genus of about 500 species of annual, biennial and perennial herbs.Many of the species have leaves divided into five leaflets arranged palmately (like the fingers of a hand), whence the name cinquefoil (French, cinque feuilles, “five leaves”), though some species (e.g. P. sterilis) have just three leaflets, and others (e.g. P. anserina) up to 15 or more leaflets arranged pinnately. The leaves of some cinquefoils are eaten by the larvae of some Lepidoptera species.

 

click to see the pictures…..>…...(01)...(1).……(2)....

The roots are long, slender rhizomes branched at the top from several crowns, from which arise the long-stalked leaves and solitary, yellow flowers that close up at night, and threadlike, creeping stems. The stem-runners root at intervals and often attain a length of 5 feet or more, spreading over a wide area. The name Five-leaf or Five Fingers refers to the leaves being divided into five leaflets. Each of these is about 1 1/2 inch long, with scattered hairs on the veins and margin. The margins of the leaflets serrated. In rich soils the leaflets are often six or seven. Flowers bloom in late May thru August. Harvest edible young shoots and leaves before flowers bloom. Gather entire plant, in bloom, dry for later herb use.

Recent genetic research has resulted in a number of changes to the circumscription of Potentilla (Eriksson et al., 2003).

The genera Duchesnea, Horkelia, and Ivesia, previously all regarded as distinct, have been shown to be members of Potentilla, though this change has not been universally adopted.

Conversely, the shrubby plant previously included in this genus as Potentilla fruticosa, does not to belong to Potentilla at all, and is now treated in the genus Dasiphora as Dasiphora fruticosa.

The two species formerly treated as Potentilla palustris and Potentilla salesowianum are now separated into the genus Comarum, while Potentilla tridentata is transferred to Sibbaldiopsis as Sibbaldiopsis tridentata, and Potentilla arguta is similarly now separated into the genus Drymocallis as Drymocallis arguta.

The silverweeds are also separable into the new genus Argentina, though these are closer to the typical species of Potentilla, and this separation is less well supported.

Potentilla is also related to the genera Geum and Dryas, and also to the strawberries in the genus Fragaria; Potentilla differs from the strawberries in having dry, inedible fruit (hence the name “barren strawberry” for some species).

Some species are grown as garden plants.

Cultivation: Cinquefoil is easily grown, prefers full sun but tolerating shade, in any moderately good well-drained soil. Sow seed early spring or autumn.

Collection and Harvesting :The best time to harvest and collect cinquefoil is in the month of June at the peak of summer. During collection, all the discolored or insect eaten leaves are rejected and only whole and undamaged parts are collected – it’s normal to uproot the entire plant. The proper way to dry cinquefoil is in shady sites.

Constituents: Cinquefoil contains tannins, resins, starches, glycine, tormentol, choline, amino acids, minerals (calcium, iron, sulfate, magnesium, potassium, silica, sodium), red pigment, vitamin C, bioflavonoids.

Medicinal Properities and Uses:
Cinquefoil is edible and medicinal, young shoots and leaves are edible in salad or cooked as a pot herb. The plant contains large amounts of tannins making it very astringent. A medicinal infusion made from the root is used in alternative medicine as an astringent, antiseptic, and tonic, used as a mouthwash for “thrash” and taken for dysentery and diarrhoea. A medicinal tonic is used for fevers and debility. A decoction is odontalgic, used as a gargle for loose teeth, spongy gums and, periodotal disease. Fresh juice mixed with honey removes hoarseness and relaxes sore throat, is very medicinal for coughs. A strong decoction is poured over infections, sores, rashes and as a bath additive it is soothing for reddened or irritated skin. An infusion of the leaves makes an excellent skin cleansing lotion and is also used cosmetically as a soothing lotion for reddened skin and for babies delicate skin. Powdered or crushed root stops bleeding. The plant is an ingredient in many anti-wrinkle cosmetic preparations for the skin.

The use of remedies made from the cinquefoil has a long history. Traditionally, cinquefoil was being employed as an herbal astringent and an anti-hemorrhagic agent. It was also a very common folk remedy for treating fevers and related problems in the body. The main anti-bleeding agent in the cinquefoil is the tannic acid present in the extracts of the herb, though the early traditional users of the herb were not aware of this fact. The presence of tannic acid is the reason for the extreme effectiveness of the cinquefoil remedy as an herbal astringent in stopping bleeding in any part of the body. The cinquefoil has also been traditionally linked with a potent ability to cure all kinds of fevers; this has been questioned in recent years, as repeated pharmacological investigations have not shown the herb to posses this ability.

Folklore:
It was an ingredient in many spells in the Middle Ages, and was particularly used as a magic herb in love potions. In an old recipe called ‘Witches’ Ointment’ the juice of Five-leaf Grass, smallage and wolfsbane is mixed with the fat of children dug up from their graves and added to fine wheat flour.
Dose: A medicinal infusion of 1 oz. of the herb to a pint of boiling water. Take 1 cup a day.

Decoction, 1 1/2 oz. of the root, boiled in a quart of water down to a pint.

How much to take:
Cinquefoil infusion: the herbal infusion can be taken thrice a day to treat all kinds of problems. The infusion can be prepared by steeping two teaspoonfuls of the dried and powdered herb in a cup of boiling water for fifteen minutes. The infusion can be prepared fresh on a daily basis.
Herbal compress: chopped cinquefoil can be prepared into an herbal compress to relieve topical disorders. Use one to two tablespoonfuls of chopped fresh cinquefoil and boil it in half a liter – a pint – of water. Allow the herb to steep in the boiling water twenty minutes before straining and cooling. The lukewarm herbal infusion can be made into a moist compress and applied on affected areas of the body. As soon as the herbal compress dries out, it must be moistened in the infusion again – this can be repeated throughout the day for maximum relief.
Cinquefoil tincture: the cinquefoil tincture can be taken in doses of two ml thrice daily to treat a variety of problems.

Applications :
Cinquefoil is also consumed as a vegetable in Europe and other places. Tender leaves of the cinquefoil can be eaten raw, or finely chopped and added in a salad or cooked in a variety of dishes such as hotpot or vegetable soups. To make external compresses, use dried whole plants that have been dried in the shade. Compresses can also be prepared from fresh decoction – made by steeping one dried whole plant in a cup or 250 ml of water. This herbal compress is excellent for the treatment of external disorders such as suppurations and hemorrhage or bruising. Herbal cinquefoil meant for consumption can be prepared by steeping the dried whole root in a cup – 250 ml – of boiling water. This remedy can be drunk to gain relief from problems like diarrhea, gastritis or uterine hemorrhaging particularly if these problems are chronic in nature. Herbal remedies made from the cinquefoil are also effective in the treatment of fractures or cases of chronic osteoporosis in patients. Since there are no side effects associated with the use of the cinquefoil, the remedies may be used in complete safety and without fear for prolonged treatments that extend for one or two consecutive months. Such treatments are particularly beneficial when the herb is used in combination with other beneficial plants that are rich in chlorophyll content, including plants like the plantain. Cinquefoil remedies can also be combined with herbs which are rich in vitamin C, such as watercress and common sorrel for maximum effectiveness. The combination of the herbal remedies in this way permits an increase in the total volume of minerals and tannins that can be absorbed by the body at any one time during the treatment. Cinquefoil is an extremely effective herb for the detoxification of the body. Addicts to any addictive chemicals benefit from the cinquefoil as the herb helps such people to walk away from addictive alkaloids like nicotine found in tobacco and cocaine extracted from coca leaves.

Pain- Relieving -Decoction:
4 t (10g) fresh cinquefoil leaves
1 t (5 g) fresh valerian roots (if dried, use 3 t)
4 cups (1 liter) water
Boil the fresh plants for 5 minutes (or infuse for 15 minutes if they are dried). Drink 1 cup (250 ml), 4 times daily, before meals.

Effective against all kinds of pain stemming from headaches, diarrhea, neuralgia, premenstrual cramps and even contractions during childbirth.
