Smilax Medica (Sarsaparilla) vs. other species

[Guest guest]

Hi,

Following the Buhner protocol, I have bought Smilax. I used it together with

Biaxin, and honestly, find it out to be very effective. My question is that

there is a lot of Smilax species, I've got the Smilax medica from nature's

answer, but S. Buhner suggests an other. So which one is the best to be bought ?

Or are they all equivalent ?
