Tian Qi is actually Panax notoginseng, which is written in the hospital. The usage of panax pseudoginseng has nothing to do with age, but only with disease, not that it is necessary to take it at any age. Panax notoginseng has the function of activating blood circulation and resolving blood stasis, reducing swelling and pain. It is used to stop bleeding when there is bleeding, such as coughing up blood, vomiting blood, bleeding from the nose, bleeding in the stool, bleeding from collapse, traumatic bleeding, and when the bleeding is very heavy. If the symptoms of blood stasis appear, such as angina pectoris, stomach pain, joint pain or abdominal pain, and there is evidence of stasis, panax pseudoginseng is also used, regardless of age, as long as there are symptoms.
