## Overview

Artemisinin is a sesquiterpene lactone derived from Artemisia annua that disrupts cellular iron homeostasis and generates [reactive oxygen species](/ingredients/condition/antioxidant). It demonstrates potent antimalarial activity and shows promising anti-cancer properties through targeted cell death mechanisms.

## Health Benefits

• Malaria treatment: Phase III RCT showed 98% efficacy with artemisinin-based combination therapies vs. 48% for standard treatment (PMID: 32171078)
• Cancer therapy support: Phase I trials demonstrated safety at 200mg/day oral dose with anti-proliferative effects in breast and colorectal cancer
• [Anti-inflammatory](/ingredients/condition/inflammation) effects: RCT-equivalent studies showed non-inferiority to hydroxychloroquine for rheumatoid arthritis
• Lupus nephritis management: Clinical evidence supports effectiveness for recurrence inhibition
• COVID-19 symptom duration: Prospective study showed shortened treatment time

## Mechanism of Action

Artemisinin contains an endoperoxide bridge that reacts with intracellular iron, particularly heme iron in malaria parasites, generating cytotoxic free radicals and alkylating proteins. The compound disrupts [mitochondrial function](/ingredients/condition/energy) and triggers apoptosis through [oxidative stress](/ingredients/condition/antioxidant) pathways. In cancer cells, artemisinin exploits elevated iron levels to selectively induce cell death while sparing healthy cells.

## Clinical Summary

Phase III randomized controlled trials involving over 1,400 patients showed artemisinin-based combination therapies achieved 98% cure rates for uncomplicated malaria versus 48% for conventional treatments. Phase I cancer studies with 24-36 participants demonstrated safety at oral doses up to 200mg daily, with preliminary anti-proliferative effects observed in breast and colorectal cancer patients. Multiple systematic reviews confirm artemisinin's superiority over chloroquine and other antimalarials, though cancer research remains in early-stage clinical development. Current evidence strongly supports antimalarial use but cancer applications require larger controlled trials.

## Nutritional Profile

Artemisinin is a purified bioactive sesquiterpene lactone compound, not a whole food or nutritional ingredient; it contains no meaningful macronutrients (carbohydrates, fats, proteins), dietary fiber, vitamins, or minerals in pharmacologically relevant doses. Key bioactive compound: Artemisinin (C15H22O5, MW 282.33 g/mol) — the defining constituent, characterized by an endoperoxide bridge (1,2,4-trioxane ring) essential for biological activity. Typical therapeutic doses range from 200–500 mg/day in clinical settings. Bioavailability: Oral bioavailability is approximately 32% due to extensive first-pass hepatic [metabolism](/ingredients/condition/weight-management); peak plasma concentration (Cmax) reached within 1–2 hours post-ingestion. Half-life: approximately 2–3 hours. The compound undergoes auto-induction of CYP2B6 and CYP3A4 enzymes, reducing plasma levels with repeated dosing by up to 50–70% after 5–7 days. Semi-synthetic derivatives (artesunate, artemether, dihydroartemisinin) exhibit improved bioavailability of 80–90%. No clinically significant micronutrient content. Fat-soluble properties enhance absorption when taken with lipid-containing food, increasing AUC by approximately 30%. Concentrated plant-source (Artemisia annua) aerial parts contain approximately 0.01–0.8% artemisinin by dry weight, alongside minor flavonoids (artemetin, casticin) and essential oils, but isolated pharmaceutical-grade artemisinin is a single purified compound.

## Dosage & Preparation

Clinically studied doses: Oral artemisinin 200mg/day for cancer; IV artesunate up to 18mg/kg MTD; standard ACT regimens for malaria vary by specific derivative. Artemether predicted at 240mg for therapeutic plasma levels. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Common side effects include nausea, vomiting, and dizziness, occurring in 10-15% of patients at therapeutic doses. Artemisinin may interact with CYP2B6 and CYP3A4 enzymes, potentially affecting [metabolism](/ingredients/condition/weight-management) of warfarin, rifampin, and certain antiretrovirals. The compound is contraindicated during first trimester pregnancy due to potential embryotoxicity, though WHO considers it safe after 13 weeks gestation. Patients with severe hepatic impairment should use caution as artemisinin undergoes extensive liver metabolism.

## Scientific Research

Large-scale phase III RCTs (n=1100) across Southeast Asia demonstrated artemisinin-based combination therapies achieved 98% cure rates for drug-resistant malaria (PMID: 32171078). Meta-analyses of 5 RCTs (n=772) confirmed comparable efficacy to other antimalarial combinations (PMID: 33013398), while phase I cancer trials established safety profiles for oral (200mg/day) and IV (18mg/kg) formulations.

## Historical & Cultural Context

Artemisinin derives from *Artemisia annua*, used in Traditional Chinese Medicine for over 2,000 years to treat fevers including malaria-like 'intermittent fever.' Historical texts like 'Zhou Hou Bei Ji Fang' (340 AD) describe hot-water extraction methods for treating chills and fevers.

## Synergistic Combinations

## Frequently Asked Questions

### What is the effective dose of artemisinin for malaria?

Standard artemisinin-based combination therapy uses 4mg/kg body weight daily for 3 days, typically 240-480mg total dose for adults. This dosing achieves rapid parasite clearance within 48-72 hours when combined with partner drugs like lumefantrine or mefloquine.

### Can artemisinin cure cancer?

Artemisinin shows promising anti-cancer activity in laboratory and early clinical studies but is not a proven cancer cure. Phase I trials demonstrate safety and some tumor response, but larger Phase II/III trials are needed to establish efficacy compared to standard cancer treatments.

### How long does artemisinin stay in your system?

Artemisinin has a short half-life of 2-3 hours and is rapidly metabolized by the liver into dihydroartemisinin, the active metabolite. Complete elimination occurs within 24 hours, requiring multiple daily doses during malaria treatment to maintain therapeutic levels.

### Is artemisinin safe during pregnancy?

Artemisinin is contraindicated in first trimester pregnancy due to animal studies showing embryotoxicity and potential birth defects. After 13 weeks gestation, WHO considers artemisinin-based therapies safe when malaria treatment benefits outweigh potential risks to the fetus.

### What foods or supplements interact with artemisinin?

Iron supplements may enhance artemisinin's cytotoxic effects, while antioxidants like vitamin E could theoretically reduce its oxidative mechanism of action. Grapefruit juice may increase artemisinin blood levels by inhibiting CYP3A4 metabolism, though clinical significance remains unclear.

### What is the difference between artemisinin and artemisinin-based combination therapies (ACTs)?

Artemisinin is the active sesquiterpene lactone compound extracted from Artemisia annua, while artemisinin-based combination therapies (ACTs) pair artemisinin with partner drugs like lumefantrine or amodiaquine to enhance efficacy and reduce resistance. Clinical trials show ACTs achieve approximately 98% efficacy against malaria parasites compared to 48% for standard monotherapies, making them the WHO-recommended first-line treatment. The combination approach works synergistically to prevent drug resistance development.

### How does artemisinin's bioavailability compare across different supplement forms?

Artemisinin absorption is enhanced when taken with fatty foods, as it is a lipophilic compound that requires dietary fat for optimal intestinal absorption. Semi-synthetic derivatives like artesunate and artemether demonstrate improved bioavailability and more rapid onset compared to raw artemisinin extract, though they require prescription use in most countries. Oral artemisinin doses of 200mg/day in clinical trials showed measurable anti-proliferative effects, suggesting adequate absorption at therapeutic dosages.

### Who should avoid artemisinin supplementation based on current research?

Individuals with glucose-6-phosphate dehydrogenase (G6PD) deficiency should exercise caution with artemisinin due to potential hemolytic reactions, and artemisinin is contraindicated during the first trimester of pregnancy based on animal safety studies. Patients taking medications metabolized by CYP3A4 enzymes may experience interactions, as artemisinin has been shown to induce hepatic metabolism. Those with severe cardiac arrhythmias should avoid artemisinin, particularly intravenous artesunate formulations which carry additional cardiovascular risks.
