neutral, sweet, salty.
Channels (meridians) entered:
liver, stomach, large intestine
肝, 胃, 大腸.
cardio-vascular effect: injected into the lower limbs of toads, water extract of su mu could mildly constrict the blood vessels. Later using sodium nitrite could not dilate them. In vitro appropriate amount of water solution of su mu could increase the strength of constriction of the hearts of frogs.
Effect on CNS inhibition: appropriate amount of water solution of su mu, using various delivery methods, promoted sleep in mice, rabbit, and guinea pigs. Large amount created anesthesia effects even death. It can inhibit the stimulating effect of strychnine or cocaine but not the stimulating effect of morphine.
anti bacteria effects: su mu decoction of 10% posseses a strong killing effect on Staphylococcus spp. and typhoid bacillus. It is effective on Gram-negative and positive bacilli
Actions & Indications:
For vomiting, hiccups, burping, indigestion, and flatulence due to pixu (spleen deficient) or fungal infection; and for difficulty in expelling phlegm; chronic bronchitis; injuries from impact, dysentery, tetanus.

The wood contains:
brasilin 2%, which is oxidized easily into brasilein (which is the red color of su mu)

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。
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. When the fake su mu is soaked in water, the water shows light yellow, yellow or orange color.
市場上發現用木材染色偽制蘇木，該品浸熱水中，水顯淺黃色, 黃色, 橙黃色等。應注意鑒別 。
