Night sweating (abnormal sweating after going to sleep and stopping after waking up), and five heart-heat (heat in the hearts of the hands and feet, and self-consciousness of being hot in the heart and chest) are commonly attributed to Kidney-Yin deficiency. Kidney-Yin deficiency refers to the deficiency of Kidney-Yin, loss of nourishment, and internal disturbance of deficiency heat. Patients with kidney yin deficiency usually show symptoms such as lumbar and knee soreness (a feeling of soreness and weakness in the lumbar and knee areas), five heartburns and heat, hot flashes (bursts of heat), night sweats, dizziness, tinnitus, insomnia and excessive dreaming, weight loss, and dryness of the pharynx and zygomatic redness (reddish color of cheeks and zygomatic bone areas). If the patient has symptoms of kidney yin deficiency such as night sweating and five heartburns and heat, he/she may choose to take Six-flavored Di Huang Pill. Its effect is to nourish yin and tonify the kidneys, and it consists of medicines such as Radix Rehmanniae Praeparata, Rhizoma Coptidis, Radix Paeoniae Mudanensis and Poria.

It should be noted that if the patient has symptoms such as night sweating and fever, it is recommended to go to a regular medical institution for consultation, do not blindly take medication on your own, so as not to delay the condition.
