  1. My name is hoover, my 18 year old daughter, Tricia was diagnosed with herpes 3 years ago. Since then, we have moved from one hospital to another. We tried all kinds of pills, but every effort to get rid of the virus was futile. The bubbles continued to reappear after a few months. My daughter was using 200mg acyclovir pills. 2 tablets every 6 hours and 15g of fusitin cream. and H5 POT. Permanganate with water to be applied twice a day, but all still do not show results. So, I was on the internet a few months ago, to look for other ways to save my only son. Only then did I come across a comment about the herbal treatment of Dr Imoloa and decided to give it a try. I contacted him and he prepared some herbs and sent them, along with guidance on how to use them via the DHL courier service. my daughter used it as directed by dr imoloa and in less than 14 days, my daughter recovered her health.
