It is a small shrub. It grows in mountain soil, reaching a height of no more than one or two chi (approx. 30-60 cm). The leaves resemble those of Photinia serratifolia (Shinan), and flower buds emerge in April, with five or six clusters hanging down like sesame bells; the flowers are greenish-white. In June and July, it bears small fruits resembling those of Peperomia pellucida (Tianzhuzi); after frost, they turn red, looking exactly like Peperomia pellucida but larger. Commonly called "Ai Jiao Zhang" (Dwarf Camphor Tree) because its leaves resemble camphor tree leaves while its trunk is short. Mountain dwellers often dig them up to sell in markets as potted ornamental plants, hence also known as Ye Xia Hong (Red Under Leaves). Li's *Caomi* records: Ye Xia Hong is also called Ping Di Mu (Flat-ground Wood), growing five or six cun (approx. 15-20 cm) tall, with round stems and red fruits growing beneath the leaves, found in mountainous and low-lying damp areas.

Experience prescription for treating hemoptysis (coughing up blood) by Yang Chunya: Use Er Liang (approx. 75g) of Ye Di Hong (same as Ai Jiao Zhang), wash clean, and pound into a paste using a wooden mallet. Take one pig lung, wash away blood impurities, insert the pounded herb into the bronchial tubes of the lung. Boil in three bowls each of river water and well water until tender. At dawn (Wu Geng time), remove the herbs and consume the soup along with the lung. One or two doses cure the condition; repeated consumption prevents recurrence.

Tao Dianyuan told me that a certain Provincial Governor possessed a secret prescription passed down from the palace for treating hemoptysis due to labor injury, critical weakness syndromes, and chronic cough leading to consumptive disease, achieving immediate cures without exception. He tested it on many people successfully. The method uses three Qian (approx. 9g) of dried Ping Di Mu leaves and one whole pig lung with the heart attached. Wash the lung clean of blood, blanch in boiling water, open the bronchial tubes with a tile, wrap the leaves inside, and tie securely with hemp thread. Cook thoroughly in water. First drink the lung broth, then remove the medicine and eat the lung meat. If the taste is bland, dip it in light soy sauce. After consuming one lung, the disease severity naturally decreases; after three lungs, all cases were cured. However, the material used here is Ping Di Mu, which differs from Ye Xia Hong. They may be of the same species or class, sharing similar medicinal properties.

Rotten Tea Leaves and Old Tea Leaves Frosted by Winter
The *Bencao Gangmu* (Compendium of Materia Medica) records tea seeds and tea oil, but omits tea roots, rotten tea leaves, and old tea leaves frosted by winter. Therefore, these are added here.

Mouth Ulcers (Kou Lan): According to *Jiusheng Kuhai*: Decoct tea tree roots and use the liquid as tea, drinking frequently. The taste is extremely bitter, but it produces immediate effects upon consumption.
