Some natural health practitioners say that parasite infections can be treated with a cleanse comprised of herbs and supplements. Very limited research exists on whether any natural ingredients may help treat parasite infections, but some people suggest the following herbal supplements may be beneficial: anise, thyme, rosemary, cumin, marjoram, barberry, berberine, black walnut, clove oil, mint, goldenseal, grapefruit seed extract, propolis, Oregon grape, wormwood. Some animal studies suggest that the following natural ingredients may have anti-parasitic effects: thyme, rosemary, cumin, marjoram, garlic, ginger, tongkat ali, wormwood, berberine, which is found in barberry, propolis, which is made by bees. Supplementing with vitamin A, zinc, and selenium might, therefore, form part of a parasite cleanse. Eating garlic, ginger, and foods high in vitamin A may also help.
Depending on the type of parasite infection you have, some infections may clear up on their own without treatment. Limited research suggests that natural ingredients alone can treat parasitic worms, but ingredients like thyme, rosemary, garlic, ginger, and probiotics may possibly help.
