I have given myself pau d' arco enemas. i use about 6 bags of pau d' arco tea to 2 quarts of water. it is very gentle on the system & kills fungus. i sometimes make a large container of it --put it in the fridge and drink it all day long.
i sometimes give myself a Grapefruit-Seed-Extract enema - i use about 15 - 20 drops to 2 quarts of water - don't really know the correct proportion to use.
if i have too much gas stuck inside of me i make an enema using about 5 or 6 bags of peppermint tea to 2 quarts of water. i also drink mint tea after. just a few minutes later lots of gas will come out through mouth and anus.
