8 Popular Weight Loss Herbs - 2
5. Garcinia Cambogia
Garcinia cambogia contains a chemical compound called Hydroxycitric acid (HCA). HCA is much like a derivative of the same citric acid that can be found in many other citric fruits whose chemical make up is only slightly different. Studies indicate that HCA may assist in weight loss because of its ability to regulate metabolism.
Studies suggest that garcinia cambogia may assist in weight loss for the following reasons :
HCA appears to block the conversion of sugars and starches into fats, that this, HCA is believed to help inhibit fat production. HCA may suppress appetite by raising levels of certain brain chemicals such as serotonin, a key stimulator of appetite.
To date no serious side effects involving either garcinia cambogia fruit extracts or the concentrated chemical HCA have been reported.
6. Green Tea
Among its arsenal of medicinal effects, preliminary studies suggest that green tea can lower cholesterol levels and reduce amounts of harmful LDL cholesterol. These same studies suggest that green tea may also increase cardiovascular health by making blood platelets less sticky.
Green Tea contains caffeine, which stimulates the central nervous system, and tannins, which combat diarrhea. Taken in moderation, green tea settles the stomach and has mild stimulant effects. However when taken in excess, it can cause insomnia and digestive problems.
Although no conclusive dosage recommendations are available for green tea, most people take about 3 cups (750 ml) per day. However, some research suggests that up to 10 cups per day is needed to receive enough polyphenols to notice a marked increase in health.
7. Guaraná
Guaraná was used to treat diarrhea, decrease fatigue, reduce hunger, and to help arthritis.
Guaraná contains a substance similar to caffeine called guaranine. Guaranine stimulates the central nervous system, increases metabolism, and has a mild diuretic effect. It has been suggested that in combination with other herbs, guarana (guaranine) may be effective in helping to promote weight loss. This effect is probably due to an appetite suppressing mechanism, an increase in calorie burning, or both.
Guaranine, a chemical compound found in guaraná, produces many of the same effects as caffeine. Individuals with conditions that may be complicated by high caffeine intake (including insomnia, depression, and pregnancy) should consult with a physician before adding guaraná to their diet.
8. Guggul
Guggul is a resin which is produced by the stem of the commiphora mukul tree, a relatively small, thorny plant native to India.
In some studies, guggul reportedly has shown to increase the production of the thyroid hormone. Since this hormone is involved in the cells' breakdown of protein, fat, and carbohydrates, theoretically this herb should promote weight loss. However, more research is needed to substantiate the effects of guggul supplementation on weight loss.
Studies have indicated that guggul can cause side effects in some people, including diarrhea, anorexia, abdominal pain, and skin rash. Modern extracts are more purified and fewer side effects have been reported with long-term use. If you have liver disease, inflammatory bowel disease, or diarrhea use caution when taking this supplement.
