In traditional Chinese medicine, this formula is used to tonify qi, nourish yin, and generate fluids, mainly for symptoms caused by qi and yin deficiency such as palpitations, shortness of breath, spontaneous sweating, dry mouth and throat, and chest tightness. Other typical signs include sweating easily after exertion, shortness of breath, thirst with dry throat, and persistent fatigue. This formula is based on Sheng Mai Yin (Rhytmic Form) with the addition of Astragalus, thereby placing stronger emphasis on reinforcing qi and securing the exterior. It is suitable for those with chronic weakness, excessive fatigue, or qi and fluid depletion due to summer heat. It helps improve weakness, fatigue, and spontaneous sweating, while also nourishing body fluids, relieving thirst and palpitations, supporting recovery of strength and endurance, and enhancing overall resistance. As a liquid preparation, it is absorbed more quickly and is especially suitable for individuals with weak constitutions.
