Product Introduction
Earthworm, known in traditional Chinese medicine as Dilong, is a medicinal material with a long history of use. It is derived from various species of earthworms, commonly Pheretima aspergillum and Eisenia fetida. The processing involves washing, drying, and preparing the earthworms for medicinal use. Earthworm is valued for its ability to clear heat, activate blood circulation, and unblock meridians.
Main Active Ingredients
The primary active components in earthworm include lumbrokinase, a fibrinolytic enzyme, amino acids, and various trace elements. Lumbrokinase is believed to be responsible for many of the therapeutic effects, particularly its ability to dissolve thrombi and improve blood flow. These components contribute to the overall medicinal properties.
Product Application Scenarios, Usage, and Dosage
In traditional Chinese medicine, earthworm is used to treat a variety of conditions. Common applications include clearing heat from the meridians, calming internal wind, and promoting blood circulation. It's often prescribed for conditions such as stroke, arthritis, and hypertension.
The typical dosage is 3-15 grams, usually administered in decoction form. It can also be found in some patent medicines. It is important to use earthworm under the guidance of a qualified practitioner, especially for those with bleeding disorders or who are taking anticoagulant medications.
Introduction to the Source Plant, Distribution, and Growth Environment
The earthworms used medicinally are commonly found in moist soil environments. Pheretima aspergillum is prevalent in East Asia, while Eisenia fetida is more widely distributed globally. These species thrive in soil rich in organic matter, playing a crucial role in soil health and nutrient cycling. The growth environment significantly impacts the quality and composition of the earthworms.
Harvesting, Processing, and Storage
Earthworms are typically harvested during the warmer months when they are most active. The process involves collecting the earthworms from the soil, cleaning them thoroughly to remove dirt and debris, and then drying them. Drying can be done naturally by sun-drying or using artificial methods to ensure proper preservation.
Once dried, Earthworm should be stored in a cool, dry place, away from moisture and direct sunlight. Proper storage is essential to prevent spoilage and maintain the medicinal properties of the earthworm. Additionally, measures should be taken to protect it from pests, such as storing it in airtight containers.
