Exhibiting a bitter-sweet flavor, bitter almond seed is traditionally used to “descend the lung” and dispel wind, as well as to relax the muscles and resolve stagnation. It also helps regulate Qi and moisturize dryness. Entering the lung and large intestine meridians, it is believed to clear rebellious Qi, ease obstructions, relieve asthma and coughing, reduce superficial edema, and moisturize dryness in the lungs and intestines. Compared to peach kernel, bitter almond seed predominantly moves Qi with a slightly warm nature and is generally combined with other ingredients. Although renowned for its Qi-regulating power, it also imparts a nourishing effect accompanied by a subtle fragrance, making it widely applicable.
