Q: Is Artemisia annua safe?

Artemisia annua is generally safe when used as directed, but avoid use during the first trimester of pregnancy and be cautious with patients who have diabetes due to potential hypoglycemia.

Q: When should I take Artemisia annua?

Follow the recommended dosing schedule, and for malaria, initiate treatment promptly after diagnosis. For arthritis, take twice daily as directed.

Q: What results can I expect from Artemisia annua?

For malaria, expect a rapid reduction in parasite load and symptoms. For arthritis, expect improvements in pain and stiffness over several weeks with consistent use.

Q: Can Artemisia annua replace standard medical care?

No, Artemisia annua is not a substitute for standard medical care for malaria or arthritis but can be used as part of a treatment regimen under medical supervision.

Also known as: Artemisia annua, Artemisia absinthium, Sweet wormwood, Sweet annie, Sweet sagewort, Wormweed, Wormwood

Overview

Artemisia annua and Artemisia absinthium are plants from the Asteraceae family, each with distinct properties and traditional uses. Artemisia annua, native to Asia, is renowned for its antimalarial properties, primarily attributed to the compound artemisinin. Artemisia absinthium is traditionally valued for its bitter flavor and medicinal applications. Artemisia annua is primarily used in treating malaria, with artemisinin and its derivatives forming standard treatment protocols. It has also been explored for potential benefits in arthritis and other inflammatory conditions. Artemisia absinthium has been investigated for managing proteinuria in patients with IgA nephropathy. Artemisia annua contains artemisinin, a potent antimalarial compound, along with other bioactive compounds like flavones and coumarins that enhance its antimalarial activity. Research on Artemisia annua is more mature, particularly regarding its antimalarial properties, supported by numerous clinical trials and systematic reviews. Research on Artemisia absinthium is less extensive but includes some clinical trials and observational studies.

Benefits

Artemisia annua demonstrates significant antimalarial effects due to artemisinin, with systematic reviews indicating efficacy comparable to quinine. It has also shown promise in alleviating arthritis symptoms; one study reported significant improvements in pain and stiffness in osteoarthritis patients, indicated by a mean change in WOMAC score of -12.2 (SD 13.84; P=0.0159 vs placebo). Thujone-free Artemisia absinthium has shown potential in managing proteinuria in IgA nephropathy patients, reducing it from 2,340 ± 530 to 315 ± 200 mg/g (P < 0.001). Artemisinin-based therapies are particularly beneficial for malaria patients, especially those resistant to other treatments. Artemisia absinthium may offer benefits for managing proteinuria in IgA nephropathy patients. The antimalarial effects of artemisinin are clinically significant, with high efficacy rates. For arthritis, improvements in WOMAC scores and visual analog scale scores indicate clinically significant reductions in pain and stiffness, typically observed over a 12-week period.

How it works

Artemisia annua's artemisinin generates reactive oxygen species that damage the malaria parasite, leading to its death. Artemisia absinthium's mechanism for reducing proteinuria is not fully understood but may involve anti-inflammatory and immunomodulatory effects. Artemisia annua interacts with the parasite's cellular machinery and can affect human enzymes like CYP1A2, potentially leading to drug interactions. Artemisia absinthium may interact with the renin-angiotensin system and reduce TNF-α levels, contributing to its therapeutic effects. Artemisia annua primarily targets the malaria parasite, particularly Plasmodium falciparum. Artemisinin has variable bioavailability, which can be improved with combination therapies and specific formulations.

Side effects

Artemisia annua is generally safe when used as directed, but it can cause gastrointestinal side effects, hypoglycemia, and cardiovascular changes. It is contraindicated in the first trimester of pregnancy due to potential teratogenicity. Artemisia absinthium, especially thujone-free preparations, is considered safer, but long-term use and high doses can still pose risks. Common side effects include gastrointestinal complaints such as abdominal pain, diarrhea, nausea, and vomiting, as well as hypoglycemia and cardiovascular changes like bradycardia and QT interval prolongation. Uncommon side effects include rash and pain at the injection site for injectable forms. Rare side effects include cumulative neurotoxicity with prolonged use. Artemisia annua can potently inhibit the CYP1A2 enzyme, potentially interacting with other medications. It should be avoided in the first trimester of pregnancy and used with caution during lactation.

Dosage

For malaria, dried leaf A. annua is typically dosed at 500 mg twice daily for 5 days. For arthritis, A. annua extract is used at 150 mg twice daily for 12 weeks. Artemisinin-based combination therapies are often used for malaria, with dosages varying based on the specific combination and patient weight. For arthritis, dosages range from 150-300 mg of A. annua extract twice daily. There is no established maximum safe dose, but higher doses are associated with increased side effects. For malaria, treatment should be initiated as soon as possible after diagnosis. For arthritis, dosing is typically twice daily. Oral forms are common for both malaria and arthritis treatments. Bioavailability can be improved with combination therapies and specific formulations.
