Yunnan Baiyao and progesterone are two different types of medicines, the former is a Chinese medicine that activates blood circulation and removes blood stasis, and the latter is a progesterone-type western medicine, which are generally not recommended to be taken together. If you need to take them together, you need to consult your doctor in advance. Yunnan Baiyao is a kind of proprietary Chinese medicine, with the efficacy of removing blood stasis and stopping bleeding, activating blood circulation and relieving pain, detoxifying and eliminating swelling, which is mainly used in the treatment of bruises, closed fractures, stasis and pain, sores, swelling and poisoning, and soft tissue contusion, bronchiectasis and coughing up blood from tuberculosis, and bleeding from ulcer disease. Progesterone is a steroid hormone secreted by the ovary, placenta and adrenal glands, which is used for preeclampsia and habitual abortion, anovulatory dysmenorrhea and anovulatory amenorrhea, and is used in conjunction with estrogen in the treatment of menopausal syndrome. In a very small number of patients, the use of Yunnan Baiyao can lead to allergic rashes, as well as adverse reactions such as nausea, vomiting and chest tightness. If an allergic reaction occurs, it should be discontinued immediately and anti-allergic treatment should be given by a doctor if necessary. Long-term application of progesterone can cause liver function abnormalities, edema, weight gain, decreased menstrual flow or amenorrhea, and susceptibility to vaginal candida infections, etc. Attention should be paid to checking the liver function and breast examination in the course of medication. Yunnan Baiyao and progesterone used together may have drug interactions, therefore, it is generally not recommended to take together. It is recommended that patients do not blindly combine drugs on their own, should be used under the guidance of a doctor, so as not to increase the risk of medication.
