thanks. i am very familiar with giardia. my 12 year old had it when she was 2. she was miserable until she was finally diagnosed months later and treated. i do have tumeric in my cabinet. funny...i read in parasite menance book not use tumeric if giardia is suspected because it promotes liver bile flow which giardia thrive in...apparently they can live in the bile ducts. but thinking logically if i use enough tumeric to force more bile out, then maybe i could force enough of the giardia out with it...i dunno...maybe i'll give it a try especially since i've never taken it for this reason. thanks for the tip.
