I take Neem all the time, it's one of the least known things in America. I tried making Neem tea and I can't understand how Indians can drink it - it tastes like death.
Neem capsules are the way to go!
It's super cheap, has NO adverse effects and is anti-bacterial, anti-viral, anti-fungal and anti-microbial (without hurting your good gut bacteria, etc.). There are a lot of studies on it and its efficacy on the web if you look.
Glad to see that explanation, someone said minibar earlier. Here is corrected, accurate version.
