Frankincense can promote blood circulation, while myrrh can promote blood circulation. These two drugs have the effects of relieving pain, reducing swelling and promoting granulation, so they are often used together. In Gujin Pill, it is a medicine for relaxing muscles and activating collaterals, removing blood stasis and relieving pain. Sanguis Draxonis and Semen Strychni are toxic, so the dosage should be cautious (raw Semen Strychni is toxic, and processed Semen Strychni is less toxic). Personally, it is not suitable for people with yin deficiency and heat excess.
PS: It is recommended to consult a regular Chinese medicine practitioner.
