按∶方外服龙眼法，五更将不见水干龙眼，以舌在齿上取肉去核，即是舌搅华池之
法，细细嚼至渣细成膏，连口中津， 然咽下，如咽甚硬物毕，又如前法，食第二
枚，具服九枚。约有一时许，服毕方起，辰巳二时，又服九枚，未申二时，又服九枚，

栗子煮熟后食用，会导致气机阻滞、留恋于胸膈；生吃则易引发气滞并滋生虫疾；晒干后食用，能降气补益，药性专入肾经，适宜治疗肾病。
它能强健腰足、增加力量，浓固肠胃、增强耐饥能力；生嚼后涂抹于筋骨碎裂疼痛处，具有消除肿胀、祛除瘀血的显著疗效。但患有中风、水气病者切忌食用；小儿多吃会导致牙齿不生。
栗榍（栗子的壳）中内含三颗果仁的，劈开后取出中间那一粒，外敷可消散瘰疬肿块、散血、调理筋骨风痛以止痛；带毛的栗壳烧成灰，外敷治疗疔疮肿毒及火丹（丹毒）；红色栗壳煮汁饮用，可止反胃、消渴；树皮用浓水煮汁，可治沙虱溪毒。
主治（参考《痘疹合参》）：痘疹患者若将栗子煮熟少量食用，可以起到补益作用，但多吃则会导致气机窒塞停滞，不宜多食；且适宜在痘疹灌浆期食用。
荔枝感天之阳气，得地之甘味，《神农本草经》虽记载其气平，但实际上气温。新鲜时味道极甘美，富含津液，故能止渴；味甘温，能益血助营，故能改善面色；但多吃令人发热或出现鼻衄、齿痛，是因为它生于炎热方位、夏季成熟，故善于助火导致发热。
荔枝核味甘温，专入肝、肾二经；火烧存性（烧至外部焦黑内部保留药性），研末后用酒送服，可散滞气、辟寒邪、止心痛及小肠气痛、癫疝、妇人血气刺痛等，这都是因为温性能通行气血的作用。
荔枝肉，能悦泽容颜、祛烦止渴、益智健气通神，能消散无形的滞气，对于瘿瘤（甲状腺肿大等）、赤肿，多吃能消散，但过度食用也会产生虚热。荔枝花和根煎汤，是治疗咽喉痹痛的良方。荔枝核烧存性后用酒调服，治疗突发心痛、疝痛。荔枝壳烧后能解秽，种痘时宜寻求使用。
主治（参考《痘疹合参》）：荔枝肉，治疗痘疹因虚导致的腹泻、痘陷伏不起，可用此来养脾发毒，但需警惕多吃会致发热、发痒。荔枝壳煎汤，北方人用来促使痘疹发出。
龙眼禀受“稼穑”（土性）的化育，所以味甘、气平、无毒。入足太阴脾经、手少阴心经。少阴心为君主之官，藏神而主血。甘味能益血补心，使君主强盛、神明通达，五脏安宁。且甘味能补脾，脾得到补益则中气充足，化源不竭，五脏更加安宁，百邪俱避，心情愉悦、精神舒畅，耳目聪明，身体轻健、耐老。
龙眼取肉入药，是因为甘味先入脾。古方归脾汤中，其功效与人参并列奏效，《神农本草经》称其为“益智”，裨益脾所藏，补心虚而增长智慧，悦胃气以培补脾土，去除健忘与怔忡，能安神熟睡，性质不热不寒，和平可贵，能养肌肉、美容颜，多服能强志聪明，久服能轻身不老，但若肠滑、中满者忌用。
龙眼核治疗狐臭，取六枚同胡椒十四粒，一同研末，遇出汗时擦拭患处。
主治（参考《痘疹合参》）：痘疹灌浆时，可大量加入大补托毒剂中。但泄利、肠滑者宜少用。
按语：方外服用龙眼的方法：五更天将不见水的干龙眼，用舌头在牙齿上刮取果肉去核，这就是“舌搅华池”（吞咽唾液）的方法，细细咀嚼至渣滓变细成膏状，连同口中津液一起咽下，如同咽下很硬的东西一样，然后再如前法吃第二枚，每次服用九枚。大约需要一个时辰的时间，服完后再起身，辰时、巳时（上午7-11点），再服九枚，未时、申时（下午1-5点），又服九枚，临睡前又服九枚，一日四次，却耗费半天工夫。服用龙眼则心气清净，且漱口津液纳咽，这是“取坎填离”的方法，劳症（虚劳咳嗽等）患者坚持行持一个月，没有不痊愈的，这是地方秘传之法。
Chestnuts, when boiled and eaten, cause Qi stagnation and retention in the chest and diaphragm; raw consumption may induce Qi movement and generate parasites; dried consumption descends Qi and tonifies deficiency, with a specific affinity for the Kidney Meridian, making it suitable for treating Kidney diseases.
It strengthens the waist and limbs, aids strength, consolidates the intestines and stomach, and increases endurance against hunger. Chewed raw and applied to fractures or painful joints, it is miraculous in reducing swelling and dispelling blood stasis. However, those suffering from wind-stroke or water-Qi disorders must strictly avoid it. Excessive consumption by children may prevent teeth from growing.
For the chestnut husk containing three kernels inside, split open and take the single kernel in the center; applying it externally disperses scrofula swellings, moves blood, regulates wind in bones and tendons, and relieves pain. The hairy shell burned to ash, applied externally, treats carbuncles, sores, toxic swellings, and fire-dan (erysipelas). Boiling the red shell to make juice and drinking it stops regurgitation and alleviates thirst. Boiling the tree bark thickly treats sand-lice and stream-poison.
Main indications (referencing *Dou Zhen He Can*): For smallpox, cooked chestnuts eaten in small amounts provide tonification, but excessive intake causes obstruction and stagnation, which is inadvisable. It is suitable for consumption during the pustule-filling stage.
Litchi absorbs the Yang Qi of Heaven and obtains the sweet flavor of Earth. Although *Shen Nong Ben Cao Jing* states its nature is neutral, it is actually warm. When fresh, its taste is extremely sweet and it is rich in fluids, thus it can quench thirst. Its sweet and warm nature benefits blood and assists Ying (Nutritive) Qi, thereby improving complexion. However, excessive consumption leads to fever or epistaxis and toothache because it grows in hot directions and ripens in summer, thus it tends to assist Fire and cause heat.
The litchi seed is sweet and warm, specifically entering the Liver and Kidney meridians. Burned to retain its properties, ground into powder, and taken with wine, it disperses stagnant Qi, repels cold pathogens, stops heart pain and Small Intestine Qi pain, mania-hernia, and women's blood-Qi stabbing scars. These effects are all due to the power of warmth to promote circulation.
Litchi flesh pleases the countenance, dispels vexation, quenches thirst, benefits intelligence, strengthens Qi, and unites the Spirit. It can dissipate formless stagnant Qi. For goiters, red swellings, excessive eating can resolve them, but overconsumption generates deficient heat. Decoction of flowers and roots is a divine prescription for throat bi-pain. Seeds retained their properties after burning, mixed with wine, treat sudden heart pain and hernia pain. Shells burned to resolve filth are sought for inoculation purposes.
Main indications (referencing *Dou Zhen He Can*): Litchi flesh treats diarrhea caused by deficiency in smallpox and sunken, non-rising eruptions. It nourishes the Spleen and promotes toxin eruption, but one must beware that excessive consumption causes fever and itching. Decoction of shells is used by people in the North to induce smallpox eruptions.
Longan inherits the transformation of "Jia Se" (the nature of Earth/Grains), hence its taste is sweet, nature is neutral, and it is non-toxic. It enters the Foot Taiyin Spleen Meridian and Hand Shaoyin Heart Meridian. The Shaoyin Heart is the Official of the Monarch, storing the Shen (Spirit) and governing Blood. Sweetness benefits blood and tonifies the Heart, strengthening the Monarch and clarifying the Spirit, thereby calming the Five Viscera. Furthermore, sweetness tonifies the Spleen; when the Spleen is tonified, Middle Qi becomes sufficient, the source of transformation does not deplete, the Five Viscera are further stabilized, hundred evils are repelled, the Heart is joyful and Spirit is serene, ears and eyes become clear, the body feels light, and aging is delayed.
Longan flesh is used in medicine because sweetness first enters the Spleen. In ancient formulas like Guipi Tang (Restore the Spleen Decoction), its efficacy matches that of Renshen (Ginseng). *Shen Nong Ben Cao Jing* calls it "Yi Zhi" (Benefiting Intelligence), benefiting what the Spleen stores, tonifying Heart deficiency and increasing wisdom, pleasing Stomach Qi to cultivate the Spleen, removing forgetfulness and palpitations, calming the Spirit for deep sleep. It is neither hot nor cold, peaceful and precious, nourishing muscles, beautifying the face. Long-term use strengthens will and intelligence, lightens the body, and delays aging. However, those with loose bowels or abdominal fullness should avoid it.
Longan seeds treat fox odor. Take six seeds together with fourteen grains of Hu Jiao (Black Pepper), grind them together, and apply to the area when sweating occurs.
Main indications (referencing *Dou Zhen He Can*): During the pustule-filling stage, it can be added in large doses to major tonifying and supporting agents. However, those with diarrhea or loose bowels should use it sparingly.
Note: The method for taking Longan outside of formal prescriptions: At dawn (Wu Geng), take dried Longan without adding water, scrape the flesh off the pit using the tongue against the teeth. This is the method of "tongue stirring Hua Chi" (swallowing saliva). Chew thoroughly until the residue becomes fine paste, then swallow along with oral saliva as if swallowing hard objects. Then repeat for the second fruit. Consume nine fruits at a time. This process takes about one Shi (two hours). After finishing, rise. During Chen and Si hours (7-11 AM), consume another nine. During Wei and Shen hours (1-5 PM), consume another nine. Before bed, consume another nine. Four times a day, taking half a day's effort. Taking Longan purifies the Heart Qi. Swallowing saliva is the method of "drawing Kan to fill Li." Patients with Lao Zheng (consumptive disease) who diligently practice this for one month will invariably recover. This is a secret local method.
