Dragon’s Bone has the effect of astringency and solidifying astringency. It can be used in decoction or in pills and powder, and can be used with other medicines for the treatment of premature ejaculation. Dragon’s bone has the effects of calming the mind (using drugs with heavy sedative properties to stabilize the mind), calming the liver and subduing yang (suppressing too much yang qi rising in the liver), and astringent (converting and consolidating), and is often decocted in water and taken internally or crushed into pills and powder when used in the treatment of premature ejaculation. There are many causes of premature ejaculation, which need to be identified and treated according to other symptoms, and appropriate medicines chosen. For example, kidney yin deficiency leading to premature ejaculation, accompanied by five heart-heat (heat in the hearts of the hands and feet, and self-consciousness of the heart and chest irritability and sultriness), hot flashes (bursts of heat), night sweating (abnormal sweating after going to sleep, and sweating stops after waking up), etc., can be paired with medicines such as ripened dihuang (熟地黄), huangbai (黄柏), and zhimu (知母). For patients with damp-heat accumulation and stagnation, one should be cautious in using Long Bone and avoid pairing it with Gypsum. In addition, the active ingredients of single medicine are limited and only play a supplementary role, and do not have the therapeutic effect of multi-drug pairing use. Patients who are in discomfort and need to use this medicine should go to the hospital and under the guidance of the doctor, and should not use the medicine without authorization.
