Generally, Radix Rehmanniae Pill with Conjugated Zi and Anshen Tonic Heart Pill are able to be taken together. Radix Rehmanniae Pill is a traditional Chinese medicine that warms the middle and strengthens the spleen. It is mainly used for treating symptoms such as coldness in the spleen and stomach (spleen and stomach weak and cold), vomiting and diarrhea, lack of warmth in the hands and feet, and cold pain in the epigastric region (stomach and epigastric region and abdomen feel cold and painful). Tranquilizing the Heart Pill also belongs to the category of proprietary Chinese medicines, with the effect of nourishing the heart and tranquilizing the mind (stabilizing the mind by nourishing the heart). It is mainly used for treating symptoms such as palpitation (accelerated heartbeat, often accompanied by panic), insomnia and dizziness and tinnitus, which are caused by insufficient blood in the heart (insufficient blood in the heart) and internal disturbances caused by fire in the heart. Taking these two proprietary Chinese medicines together will not cause adverse drug reactions, so they can be taken at the same time under normal circumstances. In addition, there is no stipulation in the instructions of these two proprietary Chinese medicines that they should not be taken at the same time. Moreover, most of the medicines will not aggravate the deficiency fire in the patient’s body, and the tranquilizing spirit and tonifying heart pills will not cause the patient to suffer from symptoms such as deficiency cold in the spleen and stomach, so it is possible to take them at the same time. However, it is recommended to follow the doctor’s instructions on how to take them.
