Overview of the efficacy and functions of Artemisia vulgaris

Artemisia annua is a traditional Chinese medicinal material that has the functions of clearing away heat and detoxifying, reducing swelling and relieving pain, dispelling wind and removing dampness. It is often used to treat colds, fever, rheumatic joint pain, bruises and other illnesses. Its main active ingredients include volatile oils, flavonoids, etc. Modern research has also confirmed that it has certain anti-inflammatory and antibacterial effects. In terms of content structure, this article will focus on the core functions of Artemisia vulgaris, focusing on its application in traditional medicine and modern research progress. At the same time, it will take into account the precautions for use and avoid exaggerated or misleading descriptions.

The traditional medicinal value of Artemisia annua

In traditional Chinese medicine theory, Artemisia angustifolia is classified as an external medicine and a rheumatism-removing medicine, and is often used for exogenous wind-heat or rheumatic arthralgia. In folk prescriptions, the fresh product is often mashed and applied externally to relieve swelling and pain caused by injuries, or boiled in water and taken internally to treat fever and headaches at the beginning of a cold. Its nature and flavor are pungent, bitter, and slightly warm, and it belongs to the lung and liver meridian, so it has a good alleviation effect on respiratory tract inflammation and joint pain. For example, "Compendium of Materia Medica" records that it "can disperse blood stasis and unblock meridians", which reflects its characteristics of activating blood circulation and removing blood stasis.

Modern research confirms Artemisia truncatula

Recent studies have shown that the ethanol extract of Artemisia annua has inhibitory effects on common pathogenic bacteria such as Staphylococcus aureus and Escherichia coli, which is consistent with its traditional use as an anti-infection. In addition, its flavonoids, such as quercetin, have been proven to reduce joint swelling by inhibiting the release of inflammatory factors. Animal experiments show that Artemisia annua aqueous extract can significantly reduce the body temperature of fever model rats, providing scientific basis for the "heat-clearing and detoxifying" effect (see Table 1).

Precautions and contraindications for use

Although Artemisia vulgaris has a wide range of effects, it should be noted that its pungent and warm properties may aggravate the symptoms of people with yin deficiency and excessive fire. Pregnant women and those with allergies should use it with caution and avoid contact with mucous membranes when used externally. Modern pharmacology suggests that some of its components may affect the activity of liver metabolic enzymes, so long-term use requires monitoring of liver function. It is recommended to use it under the guidance of a physician, especially to avoid the risk of overdose caused by combining it with Western antipyretics.

Summary and reasonable application suggestions

Taken together, as a traditional herbal medicine, the efficacy of Artemisia vulgaris is supported by historical experience and has gradually been verified by modern science. Rational use can give full play to its antipyretic, analgesic, and anti-infective advantages, but it requires syndrome differentiation and treatment, and strict control of dosage and compatibility. Future research can further focus on the purification of its active ingredients and exploration of the mechanism to provide a more sufficient basis for clinical safety application.
