Mulberry trees have several varieties. The leaves of white mulberry are palm-sized and thick. The leaves of chicken mulberry are patterned and thin. Sub-mulberry bears fruit before growing leaves. Mountain mulberry has pointed and long leaves.
The tender roots within the soil are harvested, and the bark is peeled off for use.
Sanggen (Morus Albae Cortex) Flavor: Sweet, Pungent; Nature: Cold. The sweet flavor is strong, while the pungent flavor is mild. (Some possess a bitter taste, some a pungent taste; one must select those with a distinct pungency to meet the medicinal standard.) It can ascend and descend; it is Yin within Yang. It enters the Hand-Taiyin Lung Meridian. Xu Duan (Dipsaci Radix), Guixin (Cinnamomi Ramulus), and Maziren (Cannabis Fructus) serve as its guiding herbs. *Shennong Bencao Jing* indicates it treats internal injury. It addresses Wu Lao Liu Ji (five exhaustion and six extremes, referring to various deficiency consumptive disorders), emaciation, Beng Zhong (metrorrhagia/menorrhagia), and pulse cessation. It tonifies deficiency and benefits Qi. It treats lung asthma and distension, headache due to deficient consumption and external heat, spitting blood, thirst due to heat, edema, abdominal fullness, and cutaneous swelling. It regulates middle Qi and directs rebellious Qi downward. It resolves phlegm and opens the stomach. Decocted in water and drunk, it promotes the free flow of the five Zang organs. When used in powders, it expels all wind and damp-water pathogens. Medical texts treat cough, hemoptysis, and hematemesis. Nasal obstruction, deafness, hoarseness, and oral lesions. Alternating chills and fever due to stroke. Fever due to deficient consumption. Regurgitation and hypochondriac pain. Spasmodic bi syndrome, wandering bi syndrome (arthralgia with migrating pain), and Hongjiao (podagra/foot qi). It eliminates Xiao Dao (wasting-thirst) and jaundice. Diarrhea. Obstruction of urination and defecation. Urinary incontinence. Hematuria and strangury. Intestinal borborygmus and epilepsy.
Sanggen clears fire pathogens from the Lung but does not deplete Lung Qi. Clearing pathogens is equivalent to supporting healthy Qi. (Note by Tian Yi) Although Sanggen enters the five Zang organs, it primarily focuses on the Spleen. "Internal injury" refers to damage to the Middle Earth (Spleen/Stomach), leading to extreme exhaustion of the five Zang organs. Emaciation corresponds to flesh extremity. Beng Zhong and pulse cessation correspond to pulse extremity. Tonifying deficiency means tonifying Spleen Earth deficiency; benefiting Qi means enriching the central Qi. (Note by Zhi Yi) Sweetness consolidates insufficient Yuan Qi and tonifies deficiency. Pungency drains excess Lung Qi and stops cough. (Note by Dong Yuan) Qian Yi’s Xie Bai San treats lung-heat cough and wheezing, facial swelling, and body heat. It uses one liang of stir-fried Sanggen, one liang of roasted Digupi (Lycii Cortex), and five qian of honey-fried Gancao (Glycyrrhizae Radix et Rhizoma). Take one or two qian per dose, add one hundred grains of Jingmi (Oryza Sativa Germ), decoct in water, and take warm after meals. This formula serves as the benchmark for formulas treating the Lung. Luo’s statement that it drains Lung fire pathogens rather than Lung Qi is correct. Combined with Tiandong (Asparagi Radix), Maidong (Ophiopogonis Radix), Beimu (Fritillariae Bulbus), Shashen (Glehniae Radix), Baibu (Stemonae Radix), Wuweizi (Schisandrae Fructus), Kuandonghua (Verbasci Flos), Bohe (Menthae Haplocalycis Herba), Gancao (Glycyrrhizae Radix et Rhizoma), and Pipaye (Eriobotryae Folium), it becomes an essential herb combination for treating cough. Combined with Shaoyao (Paeoniae Radix), Yiren (Coicis Semen), Mugua (Chaenomelis Fructus), Fuling (Poria), Chenni (Citri Reticulatae Pericarpium), and Chixiaodou (Vignaemen Radiatis Semen), it becomes a miraculous agent for treating edema. For severe cough with hemoptysis, take one jin of fresh Sanggen, soak in rice wash water for three nights, scrape off the yellow skin, chop finely. Add four liang of Nuomi (Oryza Sativa Japonica Group), bake until dry, and grind into powder. Take one qian per dose with rice drink. For wasting-thirst with polyuria, dig up a three-chi deep mulberry root, peel the white bark, roast until yellow-black, chop, and boil in water to make a concentrated juice, drink at will. A small amount of rice may be added, but do not use salt. For postpartum bleeding, roast Sanggen, decoct in water, and drink. For pediatric Huodan (erysipelas-like rash), bathe in juice boiled from Sanggen white bark, or apply powder mixed with sheep fat.
[Discussion] *Shennong Bencao Jing* states that Sanggen has significant tonifying effects. According to *Di Shu*, the star Jisi is the essence of Water Star, scattering to become mulberry. *Zhong Shu Shu* records that cultivating turtle shells under mulberry roots makes them grow vigorously and prevents insect damage. (Since the turtle spirit resides in Kan [Water], mulberry consumes turtles.) Guo Zizhang also stated that mulberry grows in any soil. Synthesizing these, we know this tree establishes life through the virtue of combined Earth and Water. Its nature is cold, its flavor is sweet, sweet yet pungent, similar to how Spleen Qi scatters essence upward to the Lung, which is precisely the transformation of combined Earth and Water. In the human body, Qi from Spleen and Kidney reaches the Lung and returns to the Heaven-Yang. When Yang flows freely, Yin descends naturally, allowing Mao Mai (skin and vessels) to combine essence, circulate Qi to the Fu organs, where Fu Qi becomes bright and clear, remaining in the four Zang organs. Does Sanggen’s treatment of internal injury, extreme exhaustion, emaciation, Beng Zhong, and pulse cessation, along with tonifying deficiency and benefiting Qi, not demonstrate the use of sweet-cold aided by pungency, securing Yang without obstruction so that Yin harmonizes and descends? Earth-Water combined virtue forms Yin, akin to Middle Earth following Earth Qi. Pungent-Sweet combined virtue forms Yang, akin to Middle Earth following Heaven Qi. This substance primarily treats internal injury and benefits Qi, which is its core principle. (Injury of Yang-within-Yin, such as spitting blood, thirst-heat, and labor-fever with asthma/distension, indicates Earth Qi failing to ascend and Kidney Yin failing to reach the Lung. Injury of Yin-within-Yang, such as water-Qi in the Lung, edema, and abdominal distension, indicates Heaven Qi failing to descend and Lung Yang failing to return to the Kidney.) Generally, because Sweet-Pungent harmonize, Kidney and Spleen reach the Lung together; even if Sweet-Cold harmonize, what Spleen sends to the Lung, the Lung still returns to the Kidney. This clarifies the rationale of its tonification. How can its use be limited merely to draining Lung heat and promoting water-Qi? Furthermore, if it were believed to descend more than ascend, with efficacy mainly in directing Qi downward, why would it be effective for postpartum bleeding and wasting-thirst with polyuria? This allows one to comprehend the meaning indicated in *Shennong Bencao Jing*. *Shennong Bencao Jing* prioritizes treating internal injury with Sanggen, implying that internal injury is the root of extreme exhaustion, emaciation, Beng Zhong, and pulse cessation. What is "Middle"? Humans have form, inseparable from Yin and Yang, rooted in Yin but penetrating Yang, penetrating Yang yet not leaving Yin; this is called Middle Qi, which is the Yuan Qi mentioned by Dong Yuan. Mulberry root bark adheres to the lower part, serving the function of establishing Earth and Water. Yet it possesses pungency reaching Heaven, distancing itself from Earth-Water Qi transformation to interface with the Lung, returning from Heaven to its foundational essence, descending to the lowest point. Thus, the gathering and spiritualization of ascending and descending reside in the Lung on the surface of Heaven. Therefore, its efficacy lies mostly in calming rebellious Qi, stopping cough, and stabilizing wheezing. Treating Hongjiao below involves ascending from Earth to Heaven, which then descends from Heaven to Earth, all connected by one Qi. (From Kidney combining with Middle Earth to interface with Lung, allowing Yin to flow freely in Yang; then from Lung recombining with Middle Earth to return to Kidney, allowing Yang to nurture Yin further. In this way, Yin and Yang return to origin, Ying and Wei harmonize, and its efficacy is not limited to the Lung alone.) Using Sanggen to treat edema relies on the principle that "Qi is the commander of Blood, Blood is the mother of Qi." Pre-heaven Water generates Qi, Post-heaven Qi transforms Water. When Post-heaven Qi transforms, Yin roots in Yang and Blood is generated; when Post-heaven Water transforms, Yang dwells in Yin and Qi increases. Since Water is the source of Blood, and Blood is the support of Qi, this is the practical basis for treating Beng Zhong and pulse cessation, tonifying deficiency and benefiting Qi. *Shennong Bencao Jing* prioritizes treating internal injury, deeply understanding the interdependence of Lung and Kidney, and the pivot role of Middle Earth in ascending and descending; this substance aligns with this theory.
(Attachment) White sap in the bark Treats white patches in pediatric mouth ulcers. Wipe clean and apply; it heals quickly. Also applies to injuries from metal blades causing dryness and pain; bleeding stops shortly after application.
(Attachment) Yellow fungal growth on mulberry is called Jin Sang (Golden Mulberry); the tree will eventually wither. Common in old mountain trees, rare in lake mulberries. Its flavor and nature are the same as the white bark. Its ability to clear Lung heat likely exceeds that of the white bark.
Mu氏 advises against use in cases of Lung deficiency with frequent urination. Do not use for cough caused by cold invading the Lung.
[Differentiation and Treatment] Roots exposed to air are toxic and should not be used. One must harvest tender roots from the soil, remove the woody core, scrape the thin outer bark with a copper knife, and preserve the mucus on the bark, as the medicinal power resides there. Use raw for promoting diuresis. Use honey-roasted or stir-fried for cough.
Leaf
Those regrown in summer and autumn are superior. Leaves after frost are separately collected for washing eyes.
Flavor: Bitter, Sweet; Nature: Cold. Clears chills and fever, stops sweating. (*Shennong Bencao Jing*) Promotes the five Zang organs, unblocks joints, directs Qi downward. Decoct young leaves in wine and drink to treat all wind conditions. (Ri Hua Zi) Benefits large and small intestines, clears Hongjiao edema. (Su Gong) Stops night sweats. Grind leaves after frost into powder, take with rice drink. (Dan Xi) Removes old wind and retained blood. Decoct chicken mulberry leaves, reduce to paste, and take. (Zang Qi) For wind-eye tearing, decoct mulberry leaves fallen in the twelfth lunar month, wash daily with warm liquid. Can add Mangxiao (Natrii Sulfas). Removes hand and foot wind-bi. Decoct frost-after leaves, wash with hot liquid. Lightly roast and decoct with Sangyi (mulberry husk) to treat dysentery. Also stops bleeding from all metallic wounds. (Song) Sangma Wan benefits Qi and Blood, dispels wind. Harvest mulberry leaves in April, mix with wine, steam nine times and sun-dry nine times, grind to powder. Remove shell from Huma (Sesamum indicum) or black sesame, steam nine times and sun-dry nine times, grind into paste. Mix equal parts, bind with refined honey into pills. Take five to six qian on an empty stomach with warm water. Immortals use it as a key medicine for longevity and hunger suppression. Nourishes Blood, calms Heart. One jin of old mulberry leaves, one jin of young mulberry leaf powder, eight liang of Fushen (Poria with Hostwood), processed human milk, combined to one jin, ground to powder, bound with refined honey into pills.
[Discussion] Mulberry leaf is sweet-cold, preceded by bitter, thus reaching the Fire-master Heart to promote Blood transformation. (Sweet-cold reaching Fire-generation leads to harmonious Qi and smooth Blood.) Observing therapeutic effects, most derive from the benefit of harmonizing Blood, thereby achieving wind-dispelling effects. People often attribute mulberry’s wind-treating ability to Metal controlling Wood. However, Liver belongs to Wind-Wood. The Classic states "One Yin acts as sole messenger," meaning it connects downward to Mingmen to ascend Yin-within-Yang, and upward combines with Pericardium to descend Yang-within-Yin. When sweet-cold Yin reaches the Heart master of Fire, Liver ascends its Yin-within-Yang. Then, Heart combines with sweet-cold Qi transformation, allowing Liver to descend its Yang-within-Yin. Wind disease arises either from failure of Yang to ascend or Yin to descend. Now, since Liver combines to ascend Yin-within-Yang, and receives to descend Yang-within-Yin, this is the mechanism of Metal-Wood interaction, reaching Pericardium Blood, harmonizing Liver, and extinguishing wind.
[Processing] Can be decocted, juiced, or ground into powder.
Berry
Sweet, Cold; Strong flavor, thin aroma, slightly cool nature. Nourishes Yin, tonifies Kidney, generates fluids, calms Spirit, benefits five Zang organs and joints, unblocks Blood and Qi. Ferment into wine to promote water-Qi and reduce swelling. (Due to benefitting Yin Qi) Roots are colder, berries are warmer; users should note this. (Shi Cai Note) Sweet-cold benefits Blood and clears heat. Treats fever and thirst from ingesting mineral drugs, and Small Intestine heat. Pick ripe berries, crush slightly, filter juice through cloth, boil in earthenware to thick syrup, add white honey, boil until稠, store in porcelain. Take one or two qian after meals and before sleep, dissolve in boiling water. Sangshen Wine treats hundreds of wind-heat conditions. Use three dou of berry juice, double-boil until reduced to one dan half, add two he of white honey, one liang of butter, one he of ginger juice, cook appropriately. Store in bottle. Take one he per dose, mix with wine. Can also boil juice with liquor, storing for years improves potency. For edema and distension, if water does not pass, distension overflows; if it passes, deficiency remains with recurring distension; ten out of ten die. Treat with Sangshen Wine. Slice Sangxinpi, boil two dou of water to one dou juice, add mulberry berries, boil again to obtain five sheng, ferment with five sheng of glutinous rice wine, drink.
[Discussion] Mulberry is originally sweet-cold and pungent. Forming berries, it transforms from pungent to sweet-cold; its essence gathers here. Dark red color enters Kidney and benefits Yin. Generally, for promoting water, root bark is primary; for dispelling wind, branches and leaves are superior. Regarding dark berries benefiting Yin Qi and facilitating Yin Blood, since Blood is transformed from Water, benefiting Blood promotes Water movement. Wind and Blood share the same organ, so benefiting Blood extinguishes wind. Thus, does this substance not excel in benefiting Yin?
Mu氏 advises against use for those with Spleen-Stomach deficiency-cold diarrhea due to its sweet-cold, slippery, and descending nature.
Branch
Flavor: Bitter, Neutral. Main action: Dispels wind, nourishes sinews. (Shi Cai Note) Take tender twigs, chop finely, roast until fragrant, boil in earthenware until reduced by half, transfer to silver vessel, double-boil until reduced by half, drink. Long-term use prevents hemiplegia, treats thirst and post-abscess thirst. Roasting mulberry wood unblocks joints, expels wind-cold, releases郁毒 (stagnant toxins). For carbuncles and back abscesses that do not suppurate, or necrotic tissue that does not ulcerate, as well as yin sores, scrofula, flowing abscesses, stubborn malignant sores not healing for a long time: before ulceration, it draws out toxin and relieves pain; after ulceration, it supplements Yang Qi. Split dry mulberry wood into thin slices, tie into small bundles, ignite fire and blow out, moxa/bake affected area. Blow and bake for a moment until necrotic tissue moves. Internal administration of tonifying and supporting medicines is very effective. For purple and white wind vitiligo, use ten jin of Sangzhi (Mulberry Twig), three jin of Yimucao (Leonuri Herba), five dou of water, slow boil to five sheng, strain, boil down to paste. Take half he with warm wine before sleep until cured.
Ash
Leaching ash with water yields Sangshuang (Mulberry Frost). Line a winnowing basket bottom with Sangpi paper, pour boiling water through, collect in porcelain. Double-boil until dry, alias Muyuan. Flavor: Pungent, Cold; slightly toxic. Penetrates sinews and bones. Essential for applying to carbuncles to draw out boils, and guiding other dispersing/toxic drugs to attack toxins. For body and facial edema, burn flowering mulberry branches to ash, leach juice, boil with Chixiaodou (Vignaemen Radiatis Semen), eat full meals when hungry, avoid drinking soup. Apply with Dansha (Cinnabaris), Xionghuang (Realgar), Rushiang (Boswelliae Resina), Moyao (Myrrhae Resina), Niuhuang (Bovis Calculus), Longnaoxiang (Borneolum Syntheticum), Hongbai Yaozi, Baiji (Bletillae Rhizoma), Bailian (Ampelopsis Radix) to all swellings and toxins; remarkable effect in stopping pain and drawing out toxin. Combine with Tieshu (Ferrum Oxidatum) and Chansu (Bufonis Venenum) to draw out boils.
[General Discussion] The use of Mulberry generally revolves around sweet-cold. Root white bark transforms from sweet-cold to pungent, acting on Middle Qi, thereby enriching Blood. Leaf transforms from bitter to sweet-cold, acting on Blood transformation, thereby reaching Qi. Berry uniquely possesses sweet-cold and dark color, returning to the origin of Qi and Blood, feeling strongly beneficial to Yin. Branch possesses only bitter-neutral, yet不离 (does not depart from) sweet-cold body, specifically promoting Blood transformation to extinguish wind. Generally, regarding Qi, treatment of water is precise; regarding Blood, merit in dispelling wind is specialized. These two phrases summarize it all.
