Traditional Chinese Uses

Pi Pa Ye (loquat leaf) is a cooling, bitter herb primarily used to descend rebellious Lung and Stomach Qi. For the Lungs, it clears heat, transforms phlegm, and relieves cough — particularly dry or heat-type coughs. For the Stomach, it settles upward-moving Qi to calm nausea, vomiting, and hiccup. Its descending and moistening properties make it especially helpful in hot, dry conditions.
