Fo-Ti
Uses
Parts Used & Where Grown
Fo-ti is a plant native to China, where it continues to be widely grown. It also grows extensively in Japan and Taiwan. The unprocessed root is sometimes used medicinally. However, once it has been boiled in a special liquid made from black beans, it is considered a superior and rather different medicine according to Traditional Chinese Medicine. The unprocessed root is sometimes called white fo-ti and the processed root red fo-ti. According to Chinese herbal medicine, the unprocessed root is used to relax the bowels and detoxify the blood, and the processed root is used to strengthen the blood, invigorate the kidneys and liver, and serve as a tonic to increase overall vitality.
What Are "Star" Ratings?
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Use (May Not Be Supported by Scientific Studies)
The Chinese common name for fo-ti, he-shou-wu, was the name of a Tang dynasty man whose infertility was supposedly cured by fo-ti. In addition, his long life was attributed to the tonic properties of this herb.1 Since then, Traditional Chinese Medicine has used fo-ti to treat premature aging, weakness, vaginal discharges, numerous infectious diseases, Reference angina pectoris, and Reference erectile dysfunction.
How It Works
How It Works
The major constituents of fo-ti are anthraquinones, phospholipids (e.g., lecithin), tannins, and tetrahydroxystilbene glucoside. The processed root has been used to lower cholesterol levels in Traditional Chinese Medicine. According to animal research, it helps to decrease fat deposits in the blood and possibly prevent Reference atherosclerosis.2 , 3 However, human clinical trials are lacking to support this use. Test tube studies have suggested fo-ti’s ability to stimulate Reference immune function, increase red blood cell formation, and exert an antibacterial action.4 None of these effects has been studied in humans. The unprocessed roots have a mild laxative action.
How to Use It
The typical recommended intake is 1–1 1/2 teaspoons (4–8 grams) per day.5 A tea can be made from processed roots by boiling 1/2–1 teaspoons (3–5 grams) in 1 cup (250 ml) of water for ten to fifteen minutes. Three or more cups are suggested each day. Five fo-ti tablets (500 mg each) can be taken three times per day.

Chlorphen-Pyrilamine-PE Tannts
Many drugs used in the treatment of Reference high blood pressure cause relaxation or dilation of blood vessels. Laboratory studies show that emodin, a compound in Polygonum multiflorum, also relaxes blood vessels. However, animal studies reveal that phenylephrine blocks the action of emodin.6 Controlled studies are needed to determine whether Polygonum multiflorum helps people with high blood pressure and whether phenylephrine blocks its beneficial effects.
The interaction is supported by preliminary, weak, fragmentary, and/or contradictory scientific evidence.
Side Effects
The unprocessed roots may cause mild Reference diarrhea.7 Some people who are sensitive to fo-ti may develop a skin rash. Taking more than 15 grams of processed root powder may cause numbness in the arms or legs.
