Pharmacology

Effects on lumbrici

Experiments show that Wu Mei excites lumbrici, and causes them to retreat. (3)

Effects on smooth muscles

100% Wu Mei solution has an inhibitory effect on isolated rabbit intestines, and relaxes Oddi's sphincter. Wu Mei also increases bile secretion, and renders the bile acidic. Furthermore, experiments show that Wu Mei promotes gallbladder contraction, makes it easier for bile to move along in the biliary tract, thus decreasing the chance of, and even preventing biliary tract infection and cholelithiasis. Using B-model ultrasound scanning, it is measured that 50 grams of Wu Mei in decoction can contract a healthy person's gallbladder by about 35%. (4) , (5)

Anti-microorganism effect

In-vitro experiments show that both Wu Mei decoction and Wu Mei extract have an inhibitory effect on a number of bacteria, including meningococcus, cryptocuccus, hemophilus pertussis, typhoid bacillus, paratyphoid bacillus, bacillus anthracis, colibacillus (strong inhibitory effect); hemolytic streptococci A and B, pneumococci (moderate inhibitory effect). (6)

Anti-fatigue, anti-radiation, and anti-aging effects

Wu Mei contains a large quantity of citric acid, an indispensable substance for energy conversion to take place in the human body. The presence of citric acid increases the efficacy of glucose by as much as ten-fold, releasing more energy to fight fatigue. Wu Mei also expedites the body's discharge of 90Sr, a radioactive substance, thus achieving an anti-radiation effect. Furthermore, Wu Mei increases salivary gland's secretion of parotin, promotes skin metabolism, and enhances the activity of hormone secretions, all working toward the end of delaying the aging process. (7)

Other effects

Experiments show that Wu Mei enhances immunity, inhibits JTC26 (with a 90% inhibition rate), and promotes digestion. (8) , (9) , (10)
