What Should I Do About Night Sweats?
A 49-year-old male patient developed night sweats three years ago without any apparent trigger. He would wake up finding his clothes soaked, accompanied by soreness in the waist and knees, palpitations, insomnia, and frequent dreams. No fever, cough, or bloody sputum; no significant weight loss or poor appetite. He had visited multiple hospitals and private clinics with no noticeable improvement. Symptoms worsened during busy work periods and after excessive alcohol and tobacco use.
The patient had ruddy cheeks, was lean, had hot palms and soles, a red tongue with little coating, and a fine rapid pulse. Initial diagnosis: night sweats (heart-kidney yin deficiency). Treatment focused on nourishing yin, tonifying the kidney, and calming the heart. Formula used: Liuwei Dihuang Wan with modifications: raw Rehmannia root 24g, Cornus fruit 12g, Chinese yam 12g, Alisma 9g, Moutan bark 9g, Poria 9g, Polygala root 12g, Zizyphus seed 12g, Platycladi seed 12g, Schisandra berry 9g, Dragon bone 20g (crushed), Oyster shell 20g (crushed). One dose daily, decocted and divided into two servings, taken continuously for 7 days. Symptoms improved. After another 7 days, symptoms disappeared. Continuing the same formula for 14 more days led to full recovery. Follow-up for 8 months showed no recurrence.
In Traditional Chinese Medicine, sweating during sleep is called “night sweat” or “sleep sweat”—unconscious sweating during sleep, with significant amount, ceasing upon waking. It mostly indicates yin deficiency. Clinically, patients often present with five-palm heat, insomnia, frequent dreams, ruddy cheeks, dry mouth and throat, red tongue with little coating, and fine rapid pulse—indicating yin deficiency with fire excess. Liuwei Dihuang Wan is the fundamental formula for nourishing yin and tonifying the kidney, with key diagnostic signs including soreness in the waist and knees, dizziness, hot palms and soles, red tongue with little coating, and fine rapid pulse. It can be modified for conditions such as neurasthenia, chronic nephritis, tuberculosis, diabetes, hyperthyroidism, hypertension, delayed child development, and early senile cataracts—all due to kidney yin deficiency (caution advised for those with spleen deficiency and loose stools). Raw Rehmannia nourishes the kidney and fills essence—primary herb; Cornus fruit nourishes liver and kidney while consolidating essence—secondary herb; Chinese yam tonifies the spleen and secures essence—also secondary; Alisma clears kidney fire and prevents greasiness from raw Rehmannia; Moutan bark clears liver fire and moderates the warmth of Cornus fruit; Poria promotes diuresis in spleen and kidney, assisting Chinese yam in strengthening the spleen. Together, these herbs nourish without stagnation, reduce without harming the vital energy, combining supplementation with drainage, integrating drainage within supplementation—mutually reinforcing. In this case, due to prominent night sweats and concurrent heart yin deficiency, additional herbs were added: Schisandra berry, Zizyphus seed, Platycladi seed, Polygala root, Dragon bone, and Oyster shell—to consolidate sweat and nourish the heart, calming the spirit.
