Artemisinin side effects are more pronounced in severe cases of Plasmodium falciparum malaria and when used to treat Lyme Disease. This could be caused from the death of harmful microorganisms known as a Herxheimer reaction.
Taking this supplement can also cause anaphylactic shock if allergic to members of the Asteraceae Compositae family. Avocados, chrysanthemums, daisies, marigolds and ragweed are in this family.

It would also not be given to postpartum women with blood deficiency or if experiencing diarrhea due to the cold nature of the herb.
It should not be taken with Chinese herbs Da Huang, Radix et Rhizoma Rhei, Dang Gui, Radix Angelicae Sinensis, and Sheng Di Huang, Radix Rehmanniae.
If taking as part of a cancer treatment under the direction of a doctor, wait at least two weeks after radiation treatment. And if a smoker, stop smoking for two months, otherwise the healthy cells may also be targeted.
It should also be avoided if Diabetic and if taking anti-seizure medication. Artemisinin should also not be taken with antacids, sucralfate, proton pump inhibitors, and histamine-receptor antagonists. Also don’t take with anti-viral, anti-fungal, or calcium channel blockers as side effects may occur
How Should Artemisinin be Taken?
This supplement should be taken with food. It is also recommended to take the Coenzyme Q10 (coQ10) supplement, 100 mg once a day with a meal. Cod liver oil, cottage cheese, or fish oil help to increase absorption of both of these supplements. It is also important to eat a healthy diet and get some outdoor exercise, as low calcium levels are found in cancer and chronically ill patients.
This supplement can also be taken with Vitamin C after breakfast and lunch to help with absorption of iron, leaving a 2 to 3 hour gap between taking Vitamin C and taking this supplement. The Artemisinin will target the abnormal amounts of iron in malaria, parasite and worm infections and cancer cells. Drinking green tea is also recommended.
If taking this supplement for Lyme Disease or a parasite condition, Chitosan is also recommended, unless allergic to shellfish. This helps to combat the Herxheimer reaction. It assists the body with dietary fiber, hydrates and helps prevent diarrhea.
Fatty acid supplements and fat soluble nutrients like Vitamins A, D, E and K should be taken 1 hour away from taking the Chitosan. The recommended dosage for Chitosan is 2 capsules taken 1/2 hour before one meal per day to start. Follow this dosage schedule for 2-3 days to verify tolerance. It can be increased as needed. Drinking a minimum of 8 glasses of water per day is also suggested.
Artemisinin side effects are usually few except for the noted contraindications. It is an important supplement for treating malaria, parasite conditions and for building up the immune system for febrile conditions. It is being studied currently for cancer treatment due to its selective toxicity to cancer cells and its benefit for fortifying the healthy cells.

I would like to know the same thing as the first commenter:
Why should Artemisinin not be taken with antacids? Is it dangerous or do the antacids make Artemisinin less effective?
I just found the answer to this on another website:
“Artemisia interferes with antacids, sucralfate, proton pump inhibitors, and histamine-receptor antagonists because it increases the production of stomach acid.”
Hey Kat,
Thanks for sharing that information!
I know this supplement is not FDA or even USP certified. The question I have is whether there any suppliers of artemisinin who in any way stand behind there claims of potency or purety? How does the purchaser actually know that what they are buying isn’t just ground up dry leaves of any sort? Do any certify a lack of dangerous thujone, etc.? Do any come with interaction warnings?
Hi Eugene,
Thanks for your question. The best way to validate the product is by purchasing from a manufacturer that follows cGMP guidelines and one who provides a third-party COA verifying the ingredients. You can learn more about how to pick high-quality supplements in our guide here.
