The Science: There’s only been one double-blind placebo-controlled trial of the stuff: it found that men taking fenugreek extract reported that they felt more sexual arousal and experienced better orgasms. But testosterone levels in those same men didn’t change, and the study was also tiny–only 60 participants–so it’s not clear whether there’s actually a biochemical reason for the shift or whether it was all psychological. The experiment needs to be repeated with a larger group of people to find out whether those results can be reproduced.
Impotence, or erectile dysfunction (ED), is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse. To understand the underlying causes of impotence, it helps to know the basics about how an erection develops, along with potential problems that get in the way. Erections begin in the brain with a thought related to sexual desire. Then a chemical message travels from the brain to the penis. Blood flow to the penis increases as blood vessels leading to the reproductive system relax and allow for increased circulation.
Cordyceps (Dongchongxiacao): this Chinese caterpillar fungus and the carcass of the larvae of various insects are collected in the period of the Summer Solstice (tenth solar term). They are cleaned and dried in the sun or baked and used for treating deficient kidneys manifested as impotence, seminal emissions and soreness and pain in the lower back and knees (17). Cordyceps (Dongchongxiacao) is used with Dogwood fruit (Shanzhuyu), Dioscorea (Shanyao) and Dadder seed (Tusizi). The herb can also be used alone.
Long considered an aphrodisiac by the Chinese, ginseng may do more than just rev your engine. A 2013 South Korean study found that taking the herb for just a few weeks improved guys’ performance in the bedroom, including helping them last longer before finishing. Meanwhile, a study in Spermatogenesis found that ginseng can also help make for harder, longer-lasting erections and improve testosterone levels, which in turn boosts libido. “Ginseng is a promising herbal therapy for ED because it helps promote relaxation of smooth muscle in the penis, increase dopamine levels in the brain, and increase pressure in the cavernosal nerves of the penis which helps nitric oxide synthesis,” Walker explains.

Male college students took either ginseng or a placebo, and then performed a high-intensity uphill treadmill running task. In those taking ginseng, inflammation markers were significantly decreased during recovery, suggesting that ginseng could reduce exercise-induced muscle damage.
