Saponins Health Benefits - Here's What You Need to Know

Saponins are a group of naturally occurring plant glycosides (phytochemicals), possessing detergent qualities that foam when mixed with water. In the animal kingdom, they are found in most starfish and sea cucumbers.

The presence of natural saponins has been reported in more than 100 families of plants out of which have been found to possess significant anti-cancer properties. The best-known sources are soybeans, peas, chickpeas, mung beans, peanuts, kidney beans, and lentils. Also, there are some herbs with names indicating foaming capacities such as soapbark, soapwort, and soapberry. Commercially, they derived from desert plants such as the soapbark tree and the yucca.

Interesting facts

They are widely used for their effects on ammonia emissions in animal feeding. Furthermore, they are used as vaccine adjuvants, due to their ability to modulate the cell-mediated immune system. In addition, because of their properties, they have been used in a number of cosmetics such as detergents, conditioners and shampoos, and in the photography industry as photographic emulsions.

They are highly toxic to fish, snakes, and other cold-blooded creatures.

Health benefits of saponins

Cancer prevention – latest studies have illustrated that they can lower the risk of colon cancer. Cancer cells also need cholesterol to grow and they bind cholesterol-rich cancer cell membranes, thereby limiting their growth.

Lowers bad cholesterol – saponins in yucca, legumes, and beans (all types) may lower the bad cholesterol levels (LDL) in your blood by blocking your body’s absorption of cholesterol. It is hypothesized that they either bind with bile salts or cause the bile salts to bind to the polysaccharides in dietary fiber.

Tumor – ginsenosides, a class of natural saponins which are found in the ginseng plant, have been found to suppress tumor growth and the spreading of tumor cells to other organs, according to researchers of the 2010 review.

HIV – according to a Japanese 1989 study entitled “Inhibitory effect of glycosides like soy saponins on the infectivity of HIV in vitro” by the Department of Virology and Parasitology, Japan, established that soy saponins may have inhibitory activity against HIV infection.

Antioxidant properties – they have also a direct antioxidant activity, which may protect cells against damage from exposure to oxygen, also reducing the risk of cancer and heart disease.

Mineral absorption – they aid the absorption of essential minerals and cause a lesser irritating effect on the digestive system. Research from Cornell University points out that saponins in asparagus, oats, beetroot, and spinach actually improve the body’s ability to absorb the minerals silicon and calcium.

Osteoporosis – though several discoveries have demonstrated the ginsenosides to be the most important therapeutic agent for the treatment of osteoporosis, yet the molecular mechanism of their active metabolites is not clear.

Immune system boosters – phytochemicals get rid of destructive pathogens in your body. This function naturally cleanses your body, relieves stress on your immune system and thereby allows it to function more effectively. Studies concluded that they increase the activity of natural killer cells and the activity of cytotoxic T lymphocytes (a type of white blood cells).

Saponins side effects

Due to the fact that they come from natural plant sources including yucca, alfalfa, and soy, as well as other vegetables and herbs, there are no known negative side effects from having them in your daily diet. Furthermore, their molecules are ”non-systemic”, meaning they do not penetrate the rest of the body (they do all their work within the intestinal tract), consequently having no harmful side effects.
