According to the study published in “Life Science”, a derivate from a plant called sweet wormwood can kill 98% of breast cancer in a time span as short as 16 hours! When in combination with iron, its powers are multiplied and the best part of it is that it has no effect on the healthy cells.
Artemisinin, that is contained in the plant, has been used against malaria, especially in China, and now it seems it is very successful against cancer as well. Since cancer cells have more receptors than the healthy ones, they are extremely easy to target for the power couple artemisinin and iron.
The only problem might be that the extract is expensive, but its growing popularity might eventually decrease the price.
