Introduction
Under normal circumstances, "parasite" refers to mistletoe (Viscum coloratum), which has the effects of dispelling wind, removing dampness, and promoting circulation of the meridians. If mistletoe is to be used, it must be obtained through legitimate channels as a medicinal variety, and usage and dosage should be determined according to medical advice. During daily storage, it should be kept separate from food ingredients and common plants to prevent accidental misuse. Harvesting wild mistletoe may damage tree ecosystems and makes it difficult to assess the safety of the species.

Generally, the term "parasite" refers to mistletoe, which is known for its effects of dispelling wind, eliminating dampness, and promoting circulation of the meridians. A detailed analysis is as follows:

Mistletoe is an evergreen plant that parasitizes trees such as poplars and willows and is commonly used in herbal medicine. Its active components, including flavonoids and alkaloids, are key to its therapeutic effects. Traditionally, it has been widely used to relieve rheumatic pain and arthralgia. These components help reduce joint inflammation and alleviate numbness in the limbs. Additionally, certain constituents may have immunomodulatory properties, helping to enhance the body's resistance to external stimuli. However, medicinal use requires professional processing; using raw, unprocessed mistletoe can pose health risks, so self-collection and consumption should be strictly avoided.

If mistletoe is needed for medicinal purposes, it must be obtained through legitimate channels as a properly processed medicinal product, and usage and dosage must follow medical guidance. During storage, it should be kept separate from food items and common plants to prevent accidental misuse. Collecting wild mistletoe not only harms tree ecosystems but also poses risks due to difficulty in accurately identifying safe species—such practices should be firmly avoided. If discomfort occurs after contact with untreated mistletoe, prompt medical attention is necessary, with full disclosure of exposure details.
