云溪方认为：落地花以仰开的为珍贵，山茶品种繁多，其中以千叶大红者为最佳，可入药。百草镜记载：山茶品种众多，只有宝珠山茶可入药。其花朵呈大红色，有四片大花瓣，在大花瓣中间又生出极多的小碎瓣。味道涩，在二月、三月采摘，阴干后使用。如果都是大花瓣的千叶茶称为洋茶，不入药；单瓣的也不入药。群方谱记载：宝珠山茶可以代替郁金，研成粉末后用麻油调和，涂抹于汤火灼伤处。
味微辛甘，性寒，能破血消痈，跌打损伤及吐血血症可使用它，又治疗肠风泻血、汤火伤、鼻衄（鼻出血）、炙疮，均焙干研末，空腹时取七朵用酒送服。百草镜说：具有凉血、破血、止血的功效，属于涩剂。可消除痈肿跌扑损伤，断绝久痢、肠风下血、崩漏带下、血淋、鼻衄、吐血，外敷用于炙疮。
赤痢：救生苦海记载：用大红色的宝珠山茶花，阴干研末，加白糖拌匀，在饭锅上蒸三到四次后服用。
鼻中出血：何明远方记载：千叶大红山茶花，在二月、三月采摘，阴干，用时取五、六朵，煎服即可停止出血。
又张氏必效方记载：鼻衄，用宝珠山茶中大红色的，焙干研末，取三至五钱，用滚开的砂糖水送服。
吐血咳嗽：不药良方记载：宝珠山茶在瓦片上焙至黑色，调红砂糖每日服用，不限数量。又一法：宝珠山茶十朵，红花五钱，白芨一两，红枣四两，水煎一碗服用，药渣再煎服用。红枣不拘时间，也可食用。
蒋仪药镜拾遗赋记载：山茶花是治疗吐血、衄血、肠风下血的良将。

痔疮出血：汪子明方记载：用宝珠山茶研末冲服。
Yunxi Fang states: Among fallen flowers, those facing upward are considered precious. There are many varieties of Camellia japonica (Shancha), among which the double-petaled large red variety is superior and suitable for medicinal use. Baocao Jing records: Although there are numerous varieties of Camellia japonica, only the Baozhu variety is used medicinally. Its flowers are large red with four large petals, and within these large petals grow extremely numerous small fragmented petals. The taste is astringent; it is harvested in February and March and used after shade-drying. If the double-petaled variety consists entirely of large petals, it is called Yangcha (Foreign Tea) and is not used medicinally; single-petaled varieties are also not used medicinally. Qunfang Pu records: Baozhu Camellia japonica can replace Curcuma aromatica (Yujin); when ground into powder and mixed with sesame oil, it can be applied to burns from boiling water or fire.
The taste is slightly pungent and sweet, and the nature is cold. It invigorates blood circulation and dissipates abscesses; it is used for traumatic injuries and hematemesis (vomiting blood). It also treats intestinal wind with bloody diarrhea, burns, epistaxis (nosebleed), and moxibustion sores. All are dried by roasting, ground into powder, and taken orally with wine on an empty stomach, using seven flowers. Baocao Jing states: It cools blood, invigorates blood, stops bleeding, and belongs to astringent agents. It reduces abscesses and swelling from falls and blows, stops chronic dysentery, intestinal wind with bloody stool, metrorrhagia and leukorrhea, hematuria, epistaxis, and hematemesis; externally applied to moxibustion sores.
For red dysentery: Jiusheng Kuhai records: Use large red Baozhu Camellia japonica flowers, shade-dry and grind into powder, mix evenly with white sugar, steam three to four times over a rice cooker, and take orally.
For nosebleeds: Heming Yuanfang records: Harvest double-petaled large red Camellia japonica flowers in February and March, shade-dry them, and when needed, take five or six flowers, decoct in water, and drink to stop bleeding immediately.
Another prescription from Zhangshi Bixiao Fang: For epistaxis, use the large red Baozhu Camellia japonica, roast and grind into powder, take 3 to 5 qian, and swallow with boiling sugar water.
For hematemesis and cough: Bu Yao Liangfang records: Roast Baozhu Camellia japonica on tiles until black, mix with red sugar, and take daily orally without limitation on quantity. Another method: Take ten Baozhu Camellia japonica flowers, 5 qian of Carthamus tinctorius (Honghua), 1 liang of Bletilla striata (Baiji), and 4 liang of Ziziphus jujuba (Hongzao), decoct in water to obtain one bowl, drink the liquid, and decoct the dregs again for a second dose. Jujubes can be eaten at any time as well.
Jiang Yi Yaojing Shiyi Fu states: Camellia japonica flower is an excellent general for treating hematemesis, epistaxis, and intestinal wind with bloody stool.
Song Chunhui said: I once saw someone suffering from "nipple blooming" (a condition resembling ulceration or prolapse of the nipple) that was about to fall off, with extreme pain. Someone taught him to roast Baozhu Camellia japonica, grind it into powder, mix with sesame oil, and apply topically.
For hemorrhoidal bleeding: Wang Ziming Fang records: Grind Baozhu Camellia japonica into powder and take orally with water.
