Prior administration of "Styrax Pill for Coronary Disease" proper (6 components viz., styrax liquidus, Borneolum, Lignum santali, Aristolochia, Olibanum and Cinnabaris) or the mixture of Styrax liquidus, Borneolum, Lignum Santali and Olibanum to mice prolonged the survival time of the animals subjected to low pressure hypoxia. Styrax liquidus and Borneolum administered separately showed the same effect, whereas none of the other four components showed significant protection.

用小鼠耐缺氧试验和麻醉狗冠状窦血流量及心脏动-静脉血氧差(MA-VO_2)的实验研究冠心苏合丸及其成分的作用，发现：(1)冠心苏合丸能延长小鼠耐缺氧的时间；(2)冠心苏合丸能使心肌梗塞狗的CSF回升，减少心率和MA-VO_2，对非心肌梗塞狗不能提高CSF但亦能减少心率和MA-VO_2；(3)在本实验条件下，苏合香脂和冰片似为冠心苏合丸中起作用的两个成分，其余成分如檀香、青木香、乳香或其油均未能证实其效果。
