If you think there’s one specific product you can eat that will destroy all intestinal parasites in humans and drive them out of the body, you’re deeply mistaken. Why? Because parasites are different—there are roundworms, flatworms, tapeworms, fungi, and protozoa. There’s no universal garlic, onion, pepper, tansy, or wormwood that would affect absolutely everyone. Therefore, the main task in fighting intestinal parasites in humans is not to look for some miracle product but to normalize the work of your stomach so that the acidity is normal. Secondly, you need to normalize bile outflow. If some of the parasites that you inevitably swallow die in the stomach, and all survivors die in the duodenum from normally flowing bile, you will be reliably protected from them.
