Sweet Wormwood Aerial Extract
Also known as: Sweet Wormwood, Artemether, Artemisinin, Qinghaosu, Quinghao, *Artemisia annua* L.
Overview
*Artemisia annua*, also known as Sweet Wormwood, is a plant native to Asia and Europe, recognized for its key compound, artemisinin, which has strong antimalarial properties. Traditionally, it has been used in herbal medicine to combat malaria, particularly infections by *Plasmodium falciparum*. Recent research indicates potential for broader applications, including treatment for osteoarthritis, allergies, and some cancer types. The extract is commonly available in various forms, such as capsules, teas, and extracts. While the antimalarial effects are well-established, other uses are still under investigation, with a moderate level of evidence supporting their efficacy. Overall, Sweet Wormwood holds significant promise in both traditional and modern medicine.
Benefits
The primary benefit of Sweet Wormwood is its effectiveness against malaria, particularly strains of *Plasmodium falciparum*, with evidence from clinical trials demonstrating significant improvements in treatment outcomes. Secondary benefits include potential pain reduction and improvement in stiffness in osteoarthritis patients, backed by moderate-quality studies. Additionally, some studies suggest possible antiviral properties against various viral pathogens, including SARS-CoV-2. Its benefits are most pronounced in populations suffering from malaria and osteoarthritis, where rapid improvement in symptoms is observed in malaria treatment, while longer-term effects are noted in osteoarthritis management.
How it works
Artemisinin, the principal active compound in Sweet Wormwood, exerts its antimalarial effects primarily through the induction of oxidative stress within malaria parasites, leading to cellular damage and death. The mechanism involves the endoperoxide bridge in artemisinin interacting with ferrous iron from the parasites, producing free radicals that are toxic to the pathogens. Furthermore, artemisinin can inhibit cytochrome P450 enzymes like CYP1A2, which may alter drug metabolism in patients, necessitating awareness of potential drug interactions.
Side effects
Sweet Wormwood is generally considered safe when used appropriately, but caution is warranted due to several reported side effects. Common side effects include gastrointestinal complaints (nausea, diarrhea), skin rash, and pain at injection sites. Less frequent but serious effects may include cardiovascular changes and metabolic disturbances such as hypoglycemia, especially in patients taking diabetes medications. Prolonged use carries a risk of neurotoxicity, making it essential to use this herb only as directed. Pregnant women should avoid it during the first trimester due to potential contraindications, and special caution is advised for those with diabetes or seizure disorders.
Dosage
The minimum effective dose for malaria treatment generally involves administering 500 mg of dried leaf extract twice daily for a duration of 5 days. For osteoarthritis, the optimal dosage may range around 150 mg of extract twice daily. Specific dosages can vary based on the formulation; for example, teas may have different bioavailability compared to concentrated capsules. While a maximum safe dose has not been firmly established, it is prudent to stay within the recommended usage limits to avoid the risk of adverse effects. Taking the herb with food is advised to minimize gastrointestinal discomfort.
