Wormwood
[Botanical name: Artemisia absinthium]
The wormwood shrub grows almost everywhere in the world. It has been
traditionally used in herbal medicine for years and believed to benefit
conditions like gallbladder inflammation, indigestion, parasitic infections and
poor appetite. [1,2] Its oil has been used in preparation of foods and beverages
such as absinthe, but the oil was also linked to several causes of brain
damage. [5,6]
Side effects of wormwood
Physical contact of wormwood and its pollen including its product may lead to
allergy. [7, 20-22]
Long-term use or overdoses may cause nausea, vomiting, insomnia,
restlessness, vertigo, tremors, and seizures. [3] Excessive intake of its oil may
lead to serious side effects such as seizures, brain damage or even death. [4-
6, 18, 19] Do not take wormwood without doctor's advice or during pregnancy.
Potential Health Benefits of Wormwood.
Wormwood may benefit people suffered from malaria.
Ro DK and other researchers from UCLA suggested that artemisinin, a
sesquiterpene lactone endoperoxide extracted from Artemisia annua L
(commonly known as sweet wormwood and qinghao), is highly effective against
multi-drug-resistant Plasmodium falciparum. Plasmodium falciparum is the
parasite causing malaria. [8, 13 ,15, 17]
German researchers found that application of Annual Wormwood (Artemisia
annua L.) to patients suffered from malaria would lead to a quick resolution of
parasitaemia and of clinical symptoms, but the recrudescence rate was high.
[16]
Wormwood may benefit people suffered from cancer. [9-12, 14]
Artemisinin of qinghao, sweet wormwood has been shown to have selective
toxicity towards cancer cells in vitro. [14] Researchers from University of
Washington demonstrated the potential benefits of artemisinin to prevent
breast cancer development in rats treated with a single oral dose (50mg/kg) of
7,12-dimethylbenz[a]anthracene (DMBA), known to induce multiple breast
tumors. [11]
