While I've only just started black walnut and cloves, I am also dosing myself with plenty of colloidal silver, as I read in a book that this is necessary to support your body during the parasite killing.
Cloves are an aromatic, heating medicine. They can deplete the yin. Colloidal silver, according to my health book, supports the yin. There you go. Being middle aged and depleted, I'd never dose myself daily with cloves or other heating herbs without balancing its negative aspects out. Don't worry, the cloves will still harm the parasite eggs.
Even younger people nowadays, though, suffer from yin depletion.
