CNIDIUM monnieri is now a 4:1, 10% osthole extract. A dose as little as 50mg is said to increase nitric oxide (NO) release, promote smooth muscle relaxation, and inhibit the enzyme PDE-5 (as do the leading prescription products), allowing the penis or clitoris to become filled with blood for longer periods of time. Improves sexual function when taken about an hour before sex, usually with xanthoparmelia, yohimbe, citrulline or arginine, horny goat weed, mucuna, etc. May be helpful for circulation and is found in many Chinese sleep formulas. 100-400 doses, 20 grams, $4.75 Code 883.0
XANTHOPARMELIA scabrosa (now 10:1, 7-8% alkaloidsis) a lichen said to be a natural source of a pyrimidine compound found in leading prescription medications for erectile dysfunction that inhibits PDE-5 enzyme that binds to and breaks down cGMP, the smooth muscle relaxer produced by NO. With PDE-5 inhibited, cGMP allows the penis or clitoris to remain filled with blood. May benefit general circulation. Possible dose 50-100mg, often with *883 cnidium. 200-400 doses, 20 grams, $4.50 Code 882.0
