Study Notes
Approach to Research
- Research integrates various disciplines
- Herbal, mineral, and animal substances with medicinal potential are investigated
- 380 extracts from 200 plants tested for malaria-causing Plasmodium parasite killing ability in mice
- Artemisia annua (sweet wormwood) extract initially appears promising but results are inconsistent
New Preparation Technique
- A standard method in Chinese medicine for plant preparation is decoction
- Decoction involves simmering the root of the plant
