印度黄檀能显着缩短家兔血浆的再钙化时间。黄檀素给兔1次口服50毫克／公斤，有微弱的抗凝作用（凝血酶元时间作指标）。在离体兔心灌流时，黄檀素能显着增加冠脉流量，减慢心率，轻度增加心跳振幅，不引起心律不整。去甲黄檀素作用相似。印度产降香的各种提取物（水、醇及醚）对大鼠甲醛性关节炎，有不同程度的抗炎作用。相关论述
Sandalwood from India can significantly shorten the recalcification time of rabbit plasma. Santalol, when orally administered to rabbits at a dose of 50 mg/kg, exhibits a weak anticoagulant effect (measured by thrombin time). During perfusion of isolated rabbit hearts, santalol can significantly increase coronary blood flow, decrease heart rate, slightly increase cardiac amplitude, and does not cause arrhythmia. The effects of desoxysantalol are similar. Various extracts of Indian agarwood (water, alcohol, and ether) have different degrees of anti-inflammatory effects on formaldehyde-induced arthritis in rats. This is a summary of the relevant discussions.

1. "Commentary on the Classic of Materia Medica": Benzoin is known for its intense fragrance, which has the ability to dispel all noxious influences. The variety that comes from the Philippines is reddish in color, with a sweet and non-pungent aroma. It is superior for medicinal use, while the darker purple variety is not desirable. When there is injury in the upper body, stasis of stagnant blood in the chest and ribs, pressing on it causes pain or pain in the ribs and flanks, indicating a sign of impending blood vomiting, urgent use of this medicine in powdered form for decoction is effective. It is excellent for treating internal injuries or liver damage due to anger, replacing the efficacy of turmeric. 2. "Classic of Materia Medica Revisited": Red in color, Benzoin enters the blood division and descends, therefore, when taken internally, it can promote blood circulation and resolve stasis, while when applied externally, it can stop bleeding and relieve pain. Additionally, it is suitable to add when there is deficiency leading to vomiting of blood, with a dark and dull complexion, as its function is not much different from that of Huare Shisan.
