parasites is not one thing. There are many types out there and they should be dealt differently. It does not make sense to take medicine against parasites and claim that the medicine worked without knowing if there was a parasite.
The point is to use the right tool for the job. I haven't seen anyone claim in this thread that there is no natural/hearbal medicine that will work against a parasite.
However, I have yet to see anything herbal to be proven against Entomoeba Histolytica with a hight rate of success.
I have also tried garlic. It didn't work and it made me feel worse then the alopathic medicine I took.
>before the year 1900, no human being or animal since the dawn of time has ever recovered from parasitic 'infection' due to the lack of pharmaceutical drugs.
Humans and parasites evolve. What worked before the year 1900 may not work or be out of context today.
