Herbal medicine Jiu Jeng Pushen Jiao Nang

I'm wondering if any of the more elderly members here have tried a Chinese herbal pill called Jiu Jeng Pushen Jiao Nang. A box of six pills is sold at my local pharmacy for only 290 baht, so cost is not an issue. The issues, rather, are the safety and efficacy of these pills touted by the manufacturer to be more potent than Viagra without the toxicity or side effects. An exhaustive internet search reveals only glowingly positive reviews from those selling the pills, as one might expect. I couldn't find any objective information, so I'm hoping that the voices of experience here could provide some insight into just how effective these pills are. Thanks in advance for any response.
