Earthworms, also known as dilaudid, can treat hemorrhoids because the hemorrhoid formation itself is a localized blood stasis formation and earthworms have a thrombolytic and anticoagulant effect, which has been proven in modern medicine. Many components of earthworms have a good adjustment effect on human prothrombin and human blood fibrinogen, which can treat the symptoms of hemorrhoids and can improve pain, redness and swelling. In addition, earthworms can also be used to invigorate the blood in other parts of the body, and are especially effective for the sequelae of stroke. The earthworm itself can ventilate and activate the meridians and is long in passing through them. It has a good adjusting effect on blocked meridians and poor blood circulation, and is often combined with Astragalus, Angelica and Chuan Wu in clinical practice.
