Herbal V’s active ingredients help to fight erectile dysfunction. Yohimbine, ginseng extracts and highly concentrated vitamin C (L-ascorbic acid) prevent general fatigue and stimulate blood circulation so that the erection naturally lasts longer. In combination with sexual stimulation, Herbal V increases blood flow to the penis and helps in maintaining the erection. It is also used to treat symptoms of benign prostatic hyperplasia (BPH) in men with an enlarged prostate gland. The recommended dose is one capsule taken with water approximately 30 minutes before sexual activity. The effect can last up to 7 hours.
