\”Sildenafil (Viagra) is used to treat erectile dysfunction (impotence; inability to get or keep an erection) in men. Sildenafil (Revatio) is used to improve the ability to exercise in adults with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness). Sildenafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow easily,\” (2016 The American Society of Health-System Pharmacists, Inc.)

Article.1: Research on mountain ginseng on penile erection article
This study involves in-vivo and in-vitro experiments on the smooth muscle tissues of rabbits to test the effectiveness of, specifically, mountain ginseng for erectile dysfunction. This article is heavy on scientific jargon and data, but concludes that mountain ginseng, containing constituent ginsenoside TCMG-100, is superior to red ginseng as a an alternative for erectile dysfunction. The authors do state however that more experiments are needed to see the effectiveness in human clinical trials. Pages 8 and 9, discussion section, summarizes the results found.
\”Since the first report of the clinical efficacy of Korean Red
Ginseng for ED, various types of studies have demonstrated
that whole-ginseng extracts or purified ginsenosides from ginseng
could improve ED. In particular, ginsenosides protect the
vascular endothelium against free radical-induced injury and have
a relaxing effect on vascular smooth muscle associated with NO
release from the vascular endothelium. Furthermore,
ginseng has an effect on corpus cavernosal smooth muscle with no
side effects,\” (2015, pg.2 Ho Sung Lee et al.)
\”Therefore, these results suggest that TCMG-100 can be
used as an alternative medicine to improve penile erectile function.
However, further studies using an animal model of ED are required
to elucidate its exact mechanism,\” (2015, pg.9 Ho Sung Lee et al.)
Article.2: Chinese herb formulas for treatment of erectile article
This systematic review covers 21 randomized control trials about the effectiveness of Chinese formulations on erectile dysfunction. In-depth tables of results found, as well as the Chinese formulations can be found from pages.5 to 8, and summarized conclusions can be found in the discussion section on page.17 and on-wards.
\”it has been reported that Shu gan yi yang capsule (mechanism
of soothing liver and replenishing yang) can significantly
improve the expression of endothelial nitric oxide
synthase and cyclic guanosine monophosphate and inhibit
the expression of 5’-phosphodiesterase (PDE5) in the tissue
of cavernous body of penis in ED rats,\” (2014, pg.17 Xiong, G et al.)
