Trying a product is a good way to rule in/out an issue. If parasites are an issue, then so are HCL levels in the stomach, and then gall bladder/liver as a result. Parasites can also be indicative of a dominant Th2 immune system response that can facilitate parasitic, fungal, viral, and some bacterial issues. Th2 immune responses are also usually found with excessive body burdens of chemicals and heavy metals.
