It depends on whether you sweat at night or during the day. Night sweats are mostly due to yin deficiency, while daytime sweats are mostly due to qi deficiency. You can eat Liuwei Dihuang Pills for night sweats, and buy some lily, lotus plumule, Ophiopogon japonicus, Adenophora adenophora and Lycium barbarum to drink in water. If you are sweating, you should replenish qi, such as Codonopsis pilosula and Astragalus membranaceus. Pay attention to rest, but you'd better see a doctor and dialectically take medicine.
