What are the efficacy and functions of Xuhanting Granules?

Xuhan Ting Granules are a commonly used traditional Chinese medicine belonging to the category of astringent formulations. Their core functions include reinforcing qi and nourishing yin, consolidating the exterior to stop sweating, regulating body constitution, relieving fatigue due to physical weakness, and improving sleep quality. A detailed analysis is as follows:

1. Reinforcing Qi and Nourishing Yin: The primary effect is simultaneously strengthening qi and nourishing yin, making it suitable for various discomforts caused by deficiency of both qi and yin. It helps replenish vital energy (yuan qi) and nourish bodily fluids, thereby improving diminished physiological function due to dual deficiency of qi and yin, addressing the constitutional basis of excessive sweating at its root.

2. Consolidating the Exterior and Arresting Sweating: This formula excels at astringing the surface and stabilizing defensive qi, effectively alleviating spontaneous sweating and night sweats. Whether it's spontaneous perspiration during daytime without physical activity, or night sweats that occur during sleep and stop upon waking, this granule reduces sweating by enhancing the skin’s ability to retain fluids and strengthen surface defense.

3. Regulating Body Constitution: For individuals with a constitution characterized by deficiency of both qi and yin, long-term and appropriate use can gradually improve overall constitution. It helps relieve recurrent colds, low energy, and other issues associated with physical weakness, enhances the body's adaptability to external environments, and reduces the occurrence of conditions related to constitutional deficiency.

4. Relieving Physical Weakness and Fatigue: Deficiency of qi and yin often accompanies depletion of vital energy, manifesting as limb fatigue, shortness of breath, reluctance to speak, and worsening symptoms after exertion. By reinforcing qi and nourishing yin, the granules help restore physical energy, alleviate fatigue caused by debility, and enhance vitality.

5. Improving Sleep Quality: Night sweats often lead to interrupted sleep and light sleep. This medication effectively reduces night sweating symptoms. Additionally, by restoring balance between qi and yin and stabilizing the body's internal state, it helps improve poor sleep caused by deficiency-related night sweats, promoting deeper and more restful sleep.

When using this product, attention should be paid to contraindications and precautions. Medication should be taken strictly according to medical advice and selected based on individual constitution to ensure both safety and effectiveness.
