INTRODUCTION
Plant genus Garcinia contains about 200 species of slow-growing trees and shrubs, and is a resident of the Old World tropics, especially Asia, Polynesia and South Africa. Garcinia cambogia is one of about 30 Garcinia species found in India.

TRADITIONAL APPLICATION OF GARCINIA
The fruit of the Garcinia has long been used as a spice in India, especially along the west coast, and of the Muslim population in Laos, Malaysia, Thailand and Myanmar (formerly Burma). Although the fruits are edible, they are generally considered too acidic to be eaten raw. An extract of the dried fruit is traditionally consumed for food with lamb to improve digestion. In Sri Lanka, the fruits harvested just before they are ripe, cut into chunks, sun-dried and stored for later use. In folk tradition in India, the dried fruit peel has been boiled and used against rheumatism and stomach ailments. It activates digestion and has been used as a powerful laxative to treat intestinal worms and parasites. Garcinia has also been shown to have a protective effect against gastric ulcers.

Source of drug HCA, which affects fatty acid synthesis

In 1965, Indian scientists identified a new compound, hydroksysitronsyre (hydroxycitricacid, abbreviated HCA) as a general acid in the fruit of Garcinia cambogia . Previously, the organic acids in fruit have been identified as tartarsyre and citric acid. The dried fruit shells are HCA at concentrations up to 30%. Studies in the early 1970’s showed that HCA inhibited fatty acid synthesis in rats. Further studies revealed that HCA decreased rate of lipogenesis when given intravenously or peritoneum. Given by mouth reduced the fatty acid and cholesterol synthesis only when given before meals. This led to the assumption that if the HCA to inhibit lipogenesis, but not work on the normal energy production in the human cell’s mitochondria, it could be of value to specific lipid disorders and work against obesity. Until the early 1990’s it was published several studies on the mechanism of action of HCA when it came to fat production and metabolism in rats. The studies showed that the drug reduced fatty acid synthesis in liver and fat tissue, and produced significant reduction in food intake and decreased body weight in laboratory rats.

One has also found that Garcinia can raise levels of certain chemicals in the brain, like serotonin, which is a key regulator of appetite control. The herb will thus also have a dampening effect on appetite. Unlike other diet products, does not stimulate Garcinia central nervous system to burn more calories.

HCA AS A WEIGHT-REDUCING AGENT
Experience with the use of HCA as a weight-reducing agent in humans health is mixed. In a study from 1996 of 60 obese men and women who took the supplement for eight weeks, it seemed as if the HCA helped them to lose weight, compared with a control group that received placebo. But in a subsequent 1998 study, published in the Journal of the American Medical Association (JAMA) in which 135 obese adults took Garcinia for 12 weeks, could not show any measurable weight loss. (Participants in the study took a high fiber and low-calorie diet, and some researchers believe that the fibers interfere with the absorption of the therapeutic substance HCA). To make the confusion even greater, a study from 2000 that the supplement seemed to help women lose weight, even if not curbed the appetite.

It is not known any interactions between Garcinia and food or medications. More research is needed to determine whether a diet rich in fiber, or other nutritional factors may influence the effectiveness of HCA. It is important to remember that there is no “magic pill” for weight loss. When used as a slimming agent is Garcinia often combined with other herbs and the mineral chromium. The usual dose is the ingestion of 500 mg HCA three times daily. This is taken ½ to 1 hour before each meal with plenty of water.

WARNINGS, SIDE EFFECTS AND CONTRAINDICATIONS
Garcinia has been used continuously and safely as food for centuries, and whether or not to acute or chronic poisoning of the herb. Dietary supplements containing HCA are not known to cause side effects. Diabetic patients must exercise great caution when using Garcinia, when the herb affects blood sugar. People with Alzheimer’s disease and other dementia syndrome should avoid Garcinia because of the possibility of production of acetylcholine in the brain. As with many other supplements, are not Garcinia thoroughly tested on pregnant women. If you are pregnant or planning to become, or are nursing, you should avoid supplements with Garcinia. In Ayurvedic medicine is said to Garcinia not be used at high Vata state.

Hoodia gordonii

SCIENTIFIC NAME / SYNONYMS
Hoodia gordonii
Stapelia gordonii
Gonostemon gordonii
Monothylaceum gordonii

FAMILY
Svalerotfamilien (Asclepiadaceae).

BOTANICAL DESCRIPTION
Plant genus Hoodia consists of approx. 20 species of succulents plants that grow in South Africa. They are similar, and are closely related to the flower Stapelia. Hoodia gordonii is the species that has become known as a medicinal plant. The plant usually consists of many strains. Each race has 12-14 longitudinal ribs with woody thorns that grows up to 1 cm long. The flowers are bowl-shaped, more or less round and have a brownish color. They smell like rotten meat, which attracts flies providing pollination. The plant contains a lot of brown seeds with silky hairs. Hoodia is often called a cactus, but this is wrong as the plant belongs to the succulents family and not the cactus family.

PREVALENCE
Hoodia gordonii grows in and around the Kalahari Desert in South Africa.

PLANT PARTS
The translucent part of the plant is used. The natives of Africa take a little bit of the plant, peel away the thorns and eat it fresh. In commercial preparations an extract of the plant is used. Hoodia preparations may be imported for private use, but since the species is covered by CITES (CITES is a global agreement that regulates cross-border trade in endangered species and products from endangered species), it must be for imports accompanied by a CITES permit to be presented to Customs. Without such a permit the item is seized.

INGREDIENTS
Hoodia contains a substance (a Pregnana-glycosidic) called P57, which mimics the glucose signal substance in the brain.

PROPERTIES AND EFFECT
Appetite suppressant, curbs hunger.

MAY BE USED FOR THE FOLLOWING THE HEALTH PROBLEMS / DISEASES
Obesity, allergic reactions in the eyes and stomach pains.

REVIEWS OF HOODIA
Hoodia gordonii has come under scrutiny in the West as a dietary supplement meant to be able to suppress hunger and thirst. On the internet, the herb is marketed as a “miracle cactus”, and should, according to the allegations made, be an effective diet aid. Hoodia is not a cactus but a succulent plant.

Hoodia has always been eaten by so-called “Bushmen” of South Africa. By eating a slice of Hoodia twice daily, the San people are able to repress hunger and still maintain their energy during two to three day hunting trips. That way they could bring their prey back home without eating them on the trip, which was good practice in these areas of Africa. In northern Botswana Hoodia would be provided to to children who “eat too much” to get them to reduce food intake. This is something that must be done with caution, because if this treatment is given for more than three months, the child will die. In northern Namibia, the vegetable juice of Hoodia is still used to treat allergic reactions in the eye. To treat severe stomach pain, chunks of Hoodia were bolied in water, and the brewed drink ingested.

WHY HOODIA
When scientists examined the ingredients in Hoodia Gordonii, they found that the herb contained a previously unknown substance, called P57, which has now been patented. The patent was sold to Phytopharm, a pharmaceutical company in Cambridgeshire. This company has also sold the rights to develop the medicine of the drug to the large pharmaceutical company Pfizer.

Dr. Richard Dixey of the firm Phytopharm, explains the mechanism of action of Hoodia as follows: The brain detects the intake of sugar in the hypothalamus. When you eat, your blood glucose levels increase and you feel full. Hoodia contains a compound that acts as a neurotransmitter in the same way as glucose, but seems to be 10 000 times as active as glucose. The drug fools the brain into thinking you’re full, even if you have not eaten food. It curbs your appetite so you do not feel like eating.

STUDIES ON THE EFFECTS OF HOODIA
Dixey performed the first animal trials with Hoodia. Rats, which normally eat everything, completely stopped eating after ingestion of the plant. In the first clinical trial with humans, a group of very obese people were placed in a setting that almost resembled a prison. The only thing they could do was to read newspapers, watch TV and eat. Half of the volunteers were given Hoodia and the rest a placebo. 15 days later, the group who were given Hoodia had reduced their caloric intake by 1000 calories per day. The result was interpreted as convincing.

WARNINGS, SIDE EFFECTS AND CONTRAINDICATIONS
Since Hoodia is a “new medicine” for people in western countries, one should be careful not to jump on this new “super herb.” It still needs a lot of research before the active ingredient P57 is on the market for products that are well documented in terms of efficacy and potential side effects. However, there are already many products that are made of hoodia. These are marketed through the internet, but be aware that Hoodia is an herb that is highly endangered in the wild (covered by CITES, a convention that regulates trade in endangered animals and plants and their products), and is therefore illegal to import. Consignments with hoodia arriving in the country is usually stopped at customs, and you can risk getting a fine of several thousand dollars if you try to import Hoodia.
