1. Efficacy and function: Efficacy: activate blood circulation, circulate qi, and relieve pain. It is mainly used to treat pain due to blood stasis and qi stagnation.

2. Taboo:

Corydalis Corydalis is pungent in taste and warm in nature. It attacks blood and removes stagnation. Its medicinal properties are rapid, but it has no effect of replenishing qi and has little ability to nourish blood. Therefore, it is not suitable for people with insufficient Qi, poor spleen and stomach function, and stomach and abdominal pain. If the clinical manifestations are dull complexion, chlorosis, fatigue and shortness of breath, although there is pain but no symptoms of stasis, it should not be used alone. It should be used together with Qi-enhancing products.

Corydalis Corydalis is good at breaking up qi, dispelling blood and unblocking stagnation to relieve pain, so it is not suitable for people with blood deficiency and nutrient deficiency. If the clinical manifestations include postpartum blood deficiency, early menstruation, excessive menstrual flow, dizziness, pale tongue, white coating, thin and weak pulse, etc., it should be used with caution even if there are pains in the flanks and abdomen.

Pregnant women should avoid using products that promote blood circulation and remove blood stasis, as they may harm the fetus.

Use with caution in those with Qi and Yin deficiency, menorrhagia and blood deficiency without blood stasis.
