Modern Research: 現代研究﹕	Using su mu can distinctly prolong the life span of transplanted heart and the change of the cells of the myocardum and the change of the ultrastructures of the cells are milder than the control group, and closer to that of Cyclosporin A group; thus announced by Heilongjiang Traditional Chinese Medical School. Further observation by molecular biology and immunology, su mu can inhibit T cells toxin and can reduce the host rejection reaction, thus protect the transplanted heart. 黑龍江中醫藥大學研究的結果表明，蘇木可以明顯延長移植心臟的存活時間，其心肌細胞的病理形態學和細胞超微結構的變化要明顯輕於模型對照組，接近於環孢素 A組。經分子生物學及免疫學進一步觀察，蘇木可以抑制細胞毒性T細胞釋放的穿孔素和顆粒 B的基因表達，從而減輕宿主的抗排斥反應，使被移植的心臟得到保護。
Cautions: 禁忌﹕	Not suitable in cases of  blood deficient   and without  blood stasis . Not to use in cases of pregnancy. There are fake su mu in the market. Those are dyed wood.
