Summarize the processing of Rhizoma Drynariae into processed products of Rhizoma Drynariae, and the method is sand frying. The processing of Rhizoma Drynariae has been going on in the Liu and Song Dynasties in the Northern and Southern Dynasties. See "The Theory of Leigong's Processing". Drynaria fortunei (Kunze) J．Sm, a Polypodiaceae plant, is the dried rhizome [1]. Rhizoma Drynariae is bitter in taste, warm in nature, and belongs to liver and kidney meridians. It has the effects of healing pain, tonifying kidney and strengthening bones. It can be used for traumatic stress, tendon fracture, lumbago due to kidney deficiency, flaccidity and weakness of bones and muscles, tinnitus and deafness, and loose teeth. Externally used for dispelling wind and removing spots, treating alopecia areata and vitiligo. Rhizoma Drynariae is not easy to remove, and its texture is hard and tough, which is not conducive to crushing and decocting out effective components, so its processed products are often used in clinic [1]. Rhizoma Drynariae is crispy in texture, easy to remove scales, easy to adjust and prepare, and beneficial to decocting effective components, mainly for tonifying kidney and strengthening bones and relieving pain from continuous injury [1]. Rhizoma Drynariae is oblate and bulging, light and crisp, with brown or burnt yellow surface, no scales, light brown or light brown cross section, slightly astringent taste and fragrant smell [1].
3 Processing method of making Rhizoma Drynariae In the Southern and Northern Dynasties, in the Liu and Song Dynasties, there was a method of mixing honey and steaming it ("Leigong Roasting Theory") [1].
In the Tang Dynasty, there was a method of making ginger, removing hair and frying (the secret recipe of treating wounds and removing dipsacus by immortals) [1].
In the Song Dynasty, the processing methods such as artillery (Rehabilitating Materia Medica for Zheng Zheng and Jing Shi Zheng), salt frying (General Record of Shengji), depilation, steaming with wine (Prescription of Taiping Huimin and Heji Bureau), soaking and frying with wine, baking (Annotation for Women's Prescriptions) were added [1]. And began to elaborate on the processing function, such as "Rebuilding the Herbal Medicine of Zheng He Jing Shi Syndrome", which contains: "Canned pig kidney, eaten hollow, can cure tinnitus and also stop all kinds of miscellaneous pain [1]."
In the Ming and Qing Dynasties, there were other methods such as frying black (Puji Fang), roasting (Surgical Principles), steaming with honey (Compendium of Materia Medica), steaming and baking (Compendium of Materia Medica), making charcoal (Despei Materia Medica), and frying with wine (New Edition of Augmented Prescriptions) [1]. Among them, "Grasping the Spirit Herbal Medicine" also records: "Some people drain for a long time, and the medicines are ineffective. It is kidney deficiency to stew and eat with bone fragments, and cover the kidney to control urination and defecation for a long time. You can't just wipe your teeth from the spleen and stomach ... You can't only cure the disease, but also strengthen the bones [1]."
At present, the main processing methods are sand frying [1].
Preparation of Rhizoma Drynariae Tablets: Take the original medicinal materials, remove non-medicinal parts and impurities, wash, moisten thoroughly, cut into thick slices and dry [1]. Sieve off debris [1].
The processing method of Rhizoma Drynariae is as follows: firstly, put the sand in a hot pot, heat it with strong fire, and when it reaches a flexible state, put in the Rhizoma Drynariae patch, turn it constantly, fry it until it bulges, take it out, sieve it out, let it cool, and knock it off [1].
4 The characteristics of making drynaria are irregular thick pieces, surrounded by small scales of dark brown to dark brown, soft as wool, brown or dark brown after burning, reddish brown or reddish brown on one side, and small yellow spots are arranged in a circle [1]. Hard and slightly astringent [1].
Rhizoma Drynariae is oblate and bulging, light and brittle, with brown or brown surface and no scales [1]. Light brown or light brown in cross section, slightly astringent in taste and fragrant in gas [1].
5 The nature and taste of Rhizoma Drynariae return to the Pharmacopoeia of the People's Republic of China (20 10 edition): Rhizoma Drynariae tastes bitter and warm. Liver and kidney meridians entered.

6 Efficacy and indications of Rhizoma Drynariae "Pharmacopoeia of the People's Republic of China" (20 10 edition): Rhizoma Drynariae has the effects of healing pain, tonifying kidney and strengthening bone. Externally used for dispelling wind and removing spots. It can be used for traumatic stress, tendon fracture, lumbago due to kidney deficiency, flaccidity and weakness of muscles and bones, tinnitus and deafness, and loose teeth. External treatment of alopecia areata and vitiligo.
Processing of Traditional Chinese Medicine: It has the functions of tonifying kidney, strengthening bones, and relieving pain [1].

Treat chronic diarrhea due to kidney deficiency, lumbago, rheumatic arthralgia, toothache, tinnitus, traumatic injury, bone injury, appendicitis, alopecia areata and corns.
Chinese Materia Medica: Rhizoma Drynariae has the effects of tonifying kidney and strengthening bones, promoting blood circulation and relieving pain.

7 Processing function of Rhizoma Drynariae: Rhizoma Drynariae is densely covered with scales, which is not easy to remove, and its texture is hard and tough, which is not conducive to crushing and decocting out effective components, so its processed products are often used in clinic [1].
Rhizoma Drynariae is crispy in texture, easy to remove scales, easy to adjust and prepare, and beneficial to decocting effective components, mainly for tonifying kidney and strengthening bones and relieving pain from continuous injury [1]. For example, Gu Bu Bu San (A Good Prescription for Women in School Annotation) for treating traumatic injuries and lumbago and foot pain, and Jiawei Dihuang Decoction (Herbal Huiyan) for treating tinnitus and diarrhea due to kidney deficiency [1].
Study on the Processing of Rhizoma Drynariae; Rhizoma Drynariae mainly contains naringin and dihydroflavone glycosides [1].
8. Effect of 1 on chemical constituents (1) The content of naringin in sand-scalded products and baked products of Rhizoma Drynariae is higher than that of raw products, and the stir-fried products are also slightly higher than that of raw products, indicating that after processing, the drugs become brittle and crisp, which is beneficial to the extraction of effective components [1].
(2) It is reported that the content of total flavonoids and naringin in Rhizoma Drynariae can be increased after depilation. Sand scalding, sand scalding wine processing and sand scalding salt processing do not affect the content of total flavonoids and naringin, but are beneficial to the dissolution of effective components [1].
8.2 Influence on Pharmacological Action According to the research, dihydroflavone glycosides have the effects of sedation, analgesia and enhancing myocardial contractility in rabbits; Drynaria fortunei can promote the absorption of calcium and phosphorus by bones, and increase the levels of calcium and phosphorus in serum, which is beneficial to fracture healing. Decocting with water and precipitating with alcohol can reduce blood lipid and prevent atherosclerosis [1]. Processing has a certain effect on the chemical constituents of Rhizoma Drynariae, and is beneficial to the dissolution of effective components, so it can also enhance its pharmacological action [1].
8.3 Technological research: The traditional sand-ironing method of Rhizoma Drynariae was changed to 180℃ oven baking 10 minutes until it swelled completely, and the dried Rhizoma Drynariae was knocked off or put into a sugar-coated pan or drum-type frying machine for rotation, so as to break the fluff by friction, and then it was screened out [1]. The new method can improve the quality and work efficiency of decoction pieces [1].
