Once you know which kind you have, you can target that species with either natural anti-parasitic herbs such as garlic, wormwood, fenugreek and gold-enseal, or strong antibiotics. There are different types and dosages depending on the parasite. In my experience, and I don' t usually recommend taking them, antibiotics are most effective and get the job done quickly. Afterwards, however, you' ll need to replenish the beneficial gut flora felled by the antiobiotics with high-strength probiotics like acidophilus. Whichever approach you take, heal the gut lining with glutamine (2 to 4g a day) and aloe vera juice (as directed). An anti-parasitic programme should be undertaken under the guidance of a qualified health practitioner.
