Polygonum multiflorum Seed
Research has demonstrated that Polygonum multiflorum can very significantly increase superoxide dismutase (SOD) activity. SOD is a powerful natural antioxidant and free radical scavenger that has been demonstrated to have powerful anti-aging benefits in humans. Polygonum multiflorum also inhibits b -monoamine oxidase (b -MAO). Both of these factors contribute to the anti-aging effects of this.
Polygonum multiflorum has been demonstrated to help strengthen the membranes of erythrocytes (red blood cells) and to promote the growth and development of erythrocytes. Polygonum multiflorum has been found to induce the production in human beings of g-interferon.
The tuberous root, the part of the plant used herbally under the name Polygonum multiflorum, contains lecithin and anthraquinones, free or conjugated. The root also contains more than 1.2% of a substance known as 2,3,5,4-tetrahydroxystilbene-2-0-b-D-glucoside, which is considered to be the principle active constituent.
Polygonum multiflorum is good to strengthen the muscles and tendons. It is also very beneficial for the nerves. It is used for backaches, knee joint pain, traumatic bruises, and neurasthenia. It has been used to lower blood pressure. Many people say it helps them to fall asleep at night also. The list goes on and on!
Polygonum multiflorum is a tonic for the endocrine glands, it improves health, stamina and resistance to disease. It is used to reduce cholesterol because of its lecithin.

It promotes red blood cells, helps rid intestinal parasites, and is good for resistance to cold.
Studies show that Polygonum multiflorum extract improves the cardiovascular system, enhances immune functions, slows the degeneration of glands, increases antioxidant activity, and reduces the accumulation of lipid peroxidation. Such findings suggest that Polygonum multiflorum is helpful in combating some of the processes that lead to conditions characteristic of old age, thereby also reducing the risk of fatal diseases (e.g., cancer) and incidents (e.g., heart attack, stroke). Polygonum multiflorum was shown to have effects on the antioxidant system superoxide dismutase (SOD), accumulation of lipid peroxidase, and enhancement of cell-mediated immune responses, Other antiaging substances studied extensively include, Astragalus, Epimedium, Cordyceps, Ganoderma, Iberian Ginseng, and Polygonatum (Huang Jing).
Studies have also demonstrated that various laboratory animals fed Polygonum multiflorum in their diets lived longer than control animals:
Study 1: A decoction with Polygonum multiflorum as the main ingredient prolonged the lifespan of fruit flies. At 0.1% strength, the decoction could prolong the lifespan by 5.83%. At 0.5% strength, it could prolong the lifespan by 12.03%.
Study 2: Polygonum multiflorum has been shown to slow down the aging of vital organs in aged animals, especially the reproductive organs, the ovary, the uterus and the testicle. The same formula also demonstrated significant results in open human clinical studies.
Study 3: In an attempt to prove Shou Wu`s legendary reputation as being able to reverse grey hair to black, Shou Wu liquor (dilute alcohol extract) was given to 36 people with gray hair. 24 completely recovered their dark hair and 8 more showed improvement. The total effective rate was of 88.9%.

This combination of attributes indicates that it would increase fertility in a woman and sperm in a man increase essence and blood are the two necessary qualities required to bare a child.
