Description It is an important gland of the male reproductive system whose main function is to produce an alkaline fluid. This fluid is secreted continuously, and the excess passes from the body into the urine. The rate of secretion increases greatly during sexual stimulation and the fluid contributes to the bulk of the semen. Proper prostate secretion is thus essential to proper sperm action. Dosage: Adults only can take 5 mL in 25 mL of water or juice before breakfast and again half an hour before the evening meal. Each 5 mL dose contains Epilobium parviflorum extract equivalent to dry herb 1 g.
