The efficacy of Sequoia is that it can fight cancer, because paclitaxel is a chemical extracted from Sequoia. The efficacy of redbud is that it can fight cancer, so cancer patients can also choose redbud treatment by taking redbud capsules orally, but its purity is not as high as that of paclitaxel. Therefore, the efficacy of Redbud capsules is also limited, that is, the purification of Redbud into paclitaxel, and the efficacy of single-drug paclitaxel is also limited, because the effect of single-drug paclitaxel is only about 20%, which is still effective after all. Redbud is a purified herbal medicine in nature, still available, a natural medicine to choose from. However, it does not mean that there is magic, but only that redbud is one of the drugs that can be chosen to use, and it is important to pay attention to the side effects when applying it.
