When an infection attacks your body, flushing it or eliminating it from the system is the best way to get back to normal. Pumpkin seeds are an effective remedy for giardiasis for that very reason, because pumpkin’s active ingredient, cucurbitacin, is a laxative and detoxifying compound that can help cleanse the intestinal tracts and colon. By inducing excretion and the release of gastric juices, pumpkin seeds can neutralize the parasites and naturally eliminate them from the body, thus ensuring that your nutrient uptake efficiency is no longer compromised.
