Well seems HUMAWORM said it was ok to take alot of things that include Uni da GAto and Oregano oil and MSM along with other spices to keep our in-resident worms at bay until it is time to de worm again. (Back in the 8/7/06 thread: DAY 30 etc.)
However MSM makes mine bite me furiously. And I only took 1/4 teaspoon. I guess this just makes my worms MAD instead of sleepy. Obviously can't use it.
