《本草纲目》中关于龙眼核的主治功效，大多是在谈论其果肉的功效，而对于龙眼核的作用却记载得最为广泛，仅仅提到它能治疗狐臭，其他方面都没有涉及，也没有提及它治疗脑漏（鼻渊）的功效。
黄氏医抄记载：使用广东产的圆眼（龙眼）核，放入铜炉内烧至冒烟，用筒状器具将烟熏入患病的鼻孔内，经过数次治疗即可痊愈。
治疗一切疮疥：高只元传世方记载：取龙眼核煅烧至存性（保留药性），用麻油调和后敷于患处，即可痊愈。
治疗癣疾：祝氏效方记载：取两个圆眼核，去掉外面的黑皮并捣碎，加入雄黄、硫黄、密陀僧、枯矾、川椒末，各取三钱，蘸取后擦拭患处，即可痊愈。集听方记载：患有癣疾时，用龙眼核去掉外面的黑壳，只用内核，用米醋研磨后涂抹擦拭。
灭斑生发：张觐斋说：桂圆核仁，凡是家里有小孩的人家，不可不常备。如果遇到面部磕伤或金刃（金属利器）损伤，能生肌长肉，愈合后不留疤痕；如果伤及鬓角发际处，愈合后更能重新长出头发，不像其他药物，愈合后不再长发。
治疗小肠疝气：不药良方记载：荔枝核、龙眼核各七枚，都烧成灰，大茴香二粒炒制，共同研为细末，用好酒调服；症状即可消除。经验广集记载：治疗疝气偏坠、小肠气痛，效果神妙，将荔枝核炒制、龙眼核炒制、小茴香炒制，各取等分，研为细末。空腹服用一钱，用升麻一钱，加水、酒煮开后送服。
念珠丸：张氏必效方记载：治疗阴疝偏肿，囊中疼痛难忍。乳香去油净二钱，圆眼核三钱，黄蜡二两，分为一百零八丸，以蛤粉为衣，用线穿起，露天放置一夜后收贮；遇到病症时每次服用三丸，用乳香汤送下。
小便不通：用龙眼核去掉外面的黑壳，打碎，用水煎服。如果通利之后出现欲脱（虚脱）的情况，用圆肉（龙眼肉）汤饮用。
足趾痒烂：药镜记载：用桂圆核烧成灰掺撒在患处，立即见效。
无名肿毒：黄氏医抄记载：用桂圆核用水调匀涂抹，都有效，能制止折伤出血，治疗金疮灭斑。
烟筒误伤喉部：万近蓬云记载：凡是烟管误戳伤喉部，出血不止的，用桂圆核去掉外面黑皮，只取内核仁，焙干研末，用笔管将药末吹入受伤处，即能定疼止血而痊愈，多次尝试果然灵验。
治疗刀伤出血：殷仁趾传方记载：将龙眼核炒制后捣碎，磨细敷在伤口上。
刀斧伤：黄贩翁医抄记载：桂圆核不拘多少，用火烧枯至存性，研成末掺撒在患处，即可痊愈。
按语：陈杰回生集大兴李振祖西平说：龙眼核末敷在金刃伤上，过去在西秦及巴里坤军营中，救愈了很多人，这些事迹都没有记载，可知世间有用的材料，从古至今被埋没的，数不胜数啊。
龙眼壳：是龙眼外面包裹果肉的壳，本来呈黧黄色，福建人担心它容易生虫蛀蚀，就用姜黄末拌使其变黄，而且看起来更悦目。广东地区的桂圆多不用姜黄拌，所以现在的广圆还保留本色。入药用的壳，必须洗去外面黄色的部分。
敷烫泡伤：行箧检秘记载：用圆眼壳煅烧至存性研为末，用桐油调匀涂抹患处，立即止痛，愈合后又不留斑痕，真是良方。泉州府志记载：最小的龙眼称为鬼眼，龙眼是其中等的，现在不再区分识别。
[Appendix on Shell]
In *Bencao Gangmu* (Compendium of Materia Medica), the therapeutic indications for Longan seed mostly discuss its flesh, while the extensive utility of the seed itself is barely mentioned; it only records its ability to treat fox odor (Huxiu), omitting other functions and failing to mention its treatment for nasal sinusitis (Naolou).
*Huangshi Yichao* records: Use Guangdong round-eye (Longan) seeds, burn them in a copper furnace until smoke rises, and use a tube to fumigate the affected nostril with the smoke. After several times, it will heal.
For all sores and scabies: *Gao Zhiyuan Chuan Shi Fang* records: Calcine Longan seeds to retain their medicinal properties, mix with sesame oil, and apply to the affected area. It will heal immediately.
For treating tinea (Xuan): *Zhu Shi Xiao Fang* records: Take two round-eye seeds, remove the outer black skin, crush them, add Realgar (Xionghuang), Sulfur (Liuhuang), Lead Monoxide (Mituoeng), Calcined Alum (Kufan), and Sichuan Pepper powder, each three qian. Dip and rub onto the affected area to heal. *Jiting Fang* records: For tinea, remove the outer black shell of the Longan seed, use the inner kernel, grind it with rice vinegar, and apply by rubbing.
To eliminate spots and promote hair growth: Zhang Jinzhai said: The kernels of Guiyuan seeds should be kept by every household with small children. If there are facial bumps or injuries from metal blades, they can generate flesh and heal without leaving scars; if injured at the hairline, hair can grow back after healing, unlike other medicines that do not regrow hair after healing.
For treating intestinal hernia (Xiao Chang Shan Qi): *Bu Yao Liang Fang* records: Take seven Lychee seeds and seven Longan seeds, burn them to ash, stir-fry two aniseeds, grind them together into powder, and take with good wine to dissipate the condition. *Jingyan Guangji* records: For treating hernia with unilateral swelling and intestinal qi pain, which is highly effective, stir-fry Lychee seeds, stir-fry Longan seeds, and stir-fry cumin seeds in equal parts, grind into fine powder. Take one qian on an empty stomach, delivered with water and wine boiled with one qian of Cimicifugae Rhizoma (Shengma).
Nanzhu Wan: *Zhang Shi Bixiao Fang* records: For treating yin hernia with unilateral swelling and unbearable scrotal pain. Take two qian of purified Frankincense (Ruxiang) free of oil, three qian of round-eye seeds, and two taels of Yellow Beeswax (Huangla). Divide into 108 pills, coat with Arcae Concha Powder (Gafen), string them with thread, expose overnight for storage. When symptoms occur, take three pills each time, delivered with Ruxiang decoction.
For urinary retention (Xiao Bian Bu Tong): Remove the outer black shell of Longan seeds, crush them, and decoct in water to drink. If there is a sensation of collapse after urination resumes, drink Round Flesh (Longan flesh) soup.
For itchy and rotting toe tips: *Yao Jing* records: Burn Guiyuan seeds to ash and sprinkle on the affected area for immediate effect.
For nameless swelling and toxic sores: *Huangshi Yichao* records: Mix Guiyuan seed powder with water and apply; it is effective, can stop bleeding from fractures, and treat metal wounds to eliminate spots.
For throat injury caused by pipe insertion: Wan Jinpeng Yun records: Whenever a smoking pipe accidentally punctures the throat causing unceasing bleeding, remove the outer black skin of the Guiyuan seed, take only the inner kernel, roast and grind into powder. Use a pen tube to blow the powder into the injured area. This stops pain and bleeding and heals, proven effective through repeated trials.
For treating knife wound bleeding: Yin Renzhi Chuan Fang records: Stir-fry Longan seeds, crush, grind finely, and apply.
For axe or knife wounds: Huang Fanweng Yichao records: Take any amount of Guiyuan seeds, burn until charred but retaining medicinal properties, grind into powder, and sprinkle on the affected area to heal.
Note: Chen Jie Huisheng Ji states that Li Zhenzu from Xiping, Daxing, said: Applying Longan seed powder to metal blade wounds saved many people in the military camps of Xiqin and Barkol in the past, yet these deeds were not recorded. This shows that useful materials in the world have been buried beyond count since ancient times.
Longan Shell: This is the shell wrapping the flesh of the Longan fruit, originally dark yellow. People in Fujian feared it would be easily moth-eaten, so they mixed it with Turmeric powder to make it yellow, making it more visually appealing. In Guangdong, Guiyuan is mostly not mixed with Turmeric, so current Guangdong Guiyuan retains its original color. For medicinal use, the shell must be washed to remove the external yellow color.
For applying to burns and scalds: *Xingqie Jianmi* records: Calcine round-eye shells to retain medicinal properties, grind into powder, mix with Tung Oil, and apply to the affected area. It stops pain immediately and leaves no scars after healing, truly a good prescription. *Quanzhou Fuzhi* records: The smallest Longan is called Ghost Eye, and Longan is the medium-sized one; this distinction is no longer recognized today.
