"The problem with alternative treatments for any medical problem, including erectile dysfunction, is that until you have about 20 well-controlled studies over several years, you really don't know what you are working with," cautions Richard Harris, MD, a urologist at Gottlieb Memorial Hospital, part of the Loyola University Health System in Chicago.
Ashwagandha (Withania somnifera), used widely in Ayurvedic medicine, holds a similar role to that of ginseng in Chinese medicine. Though unrelated to ginseng, it appears to share similar properties and actions. Ayurveda considers this herb to be a rasayana, or particularly powerful rejuvenative. The name ashwagandha means “like a horse,” connoting that it is regarded as a premier sexual tonic.
The medicinal plants used such as Citropsis articulata, Cannabis sativa, Cleome gynandra and Cola acuminata are frequently utilized. Some of these plants (Citropsis articulata, Cola acuminate) are already under sale for treating these conditions. Their propagation is on-going in western Uganda in places like Rukararwe Partnership Workshop for Rural Development Centre in Bushenyi District36 and researchers personal experience at Rukararwe. Rukararwe is a non-governmental organisation that is processing herbs, running a famous herbal clinic and with a medicinal plants arboretum and medicinal plants agro-forestry.
A recent study tested whether ginseng extract would influence exercise-induced muscle damage and inflammation responses. 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.
Thirty-three medicinal plants both cultivated (Table 1) and wild harvested (Table 2) were documented and identified in the area of study. In the description below these results of these two table are combined as presented below. All the identified medicinal plants in both tables belong to 25 families and 30 genera. The family Rubiaceae (4) is the most represented followed by Alliaceae, Euphorbiaceae, Mimosaceae, Papilionaceae and Caesalpinaceae families which have two species each and the rest with one species. The composition is that 42.4% are shrubs, 39.4% herbs and herb climbers and 18.2% trees. Leaves (57.6%) are the commonest plant parts followed by roots (42.1%), barks (27.3%) and the rest of the plant parts harvested have less than 10% of the parts harvested. From Allium cepa, Allium sativum, Rhus vulgaris, Warburgia ugandensis, Cleome gynandra and Tarenna graveolens, three different plant parts, are harvested for use in sexual impotence and erectile dysfunction. In the case of Impetiens species and Urtica massaica, the whole plants are harvested while the rest of the species one or two different plant parts are used. The conservation status of these documented plants is that 27.3% are cultivated while 72.7% are collected from wild places. The common methods of plant medicine preparation included boiling, chewing, pounding, cooking, roasting and smoking. The commonest method of herbal administration was by oral means as food, herbal teas or by mixing in several drinks including locally made beer.
Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.

L-arginine, an amino acid that is naturally present in the body and helps make nitric oxide, supports a successful erection. Nitric oxide is responsible for making the blood vessels relax, which helps sustain an erection for men. A 1999 study, observed the effects of six weeks of high-dose (5 grams/day) orally administered nitric oxide (NO) donor L-arginine on men with organic ED. Thirty-one percent of those who took 5 grams/day of L-arginine experienced significant improvements in sexual function. Burns told Medical Daily, “l-arginine and deer antler velvet” have been the most popular go-to natural treatments for men.
Wild oats: a study in 1986 by the Institute for Advanced Study of Sexuality in San Francisco reported effects like heightened sexual awareness, increased sexual thoughts, more orgasms (36% in men and 29% in women) and some male subjects showed increased levels of testosterone attributed to unbinding of testosterone from TBG. Oats supply steroidal saponins which modulate hormonal balance (5).
Most importantly, herbal supplements are not well regulated in the United States.  Studies have shown that 40-50% of herbal supplements do not even contain the supposed main ingredient, and many contain substances that are not listed which may have dangerous side effects2.  Another study found that over two thirds of the products tested had substituted other plant species for the plants listed on the label, and a third of products also contained other fillers or contaminants3.  A study by the New York State Attorney General of herbal products sold at GNC, Target, Walgreens, and Walmart found that four out of every five products didn’t contain the ingredient they claimed!  Fourteen US states and territories have petitioned Congress to regulate the herbal supplements industry.
A number of nonprescription products claim to be herbal forms of Viagra. Some of these products contain unknown amounts of ingredients similar to those in prescription medications, which can cause dangerous side effects. Some actually contain the real drug, which should be given by prescription only. Although the Food and Drug Administration has banned many of these products, some potentially dangerous erectile dysfunction remedies remain on the market.
