No, nothing special after garlic enema. In fact, I have been doing them before bed, and hopefully some residue stays in my colon and is soaked up into the blood stream as I sleep.
Everything I read about garlic states that it does not destroy the good bacteria, but acts as a pre-biotic, helping to maintain good bacteria. This has seems to ring true to me, since using garlic alone I did just fine with no issues like candida.
I buy most of my herbs from mountain rose, but the vidanga I have to get from a supplier in California. The ground black pepper is just grocery store peppercorns, ground in a little "magic bullet" like grinder. I also have to grind the centaury. I make all my own capsules, which is a pain and I hate it, but it does seem to work best.
The key is letting it stay in your system long enough to wear them down, like weeks even though you see no dead worms. Lately, adding the ground pepper has been what I see the difference in, if you look up piperazine, it's made from a property of ground pepper, and used to be used as an antihelminth med long ago. It also increases the potency of herbs.
The only enzymes I take on occasion are papaya enzymes, chewable and probably filled with junk. They probably don't do much for me, but I take a handful of them sometimes.
