药字从草,故神农辨药之书曰《本草经》,则本草宜以草部居先。草类甚多,孔子曰∶兰为王者之香,则
兰之于草,亦犹麒麟之于走兽,凤凰之于飞鸟,后之修本草者,苟折衷于圣人,自当以兰为冠矣。兰以素心者

晓岚先生《笔记》云∶苗峒地界值兰开时,有食兰蕊之虫,形似蜈蚣而色青,取置杯中,洒以盐末少许,覆之
以盖,须臾化为水,湛然净绿,澈如琉璃,兰气扑鼻。用以代醯,香沁齿颊,半日后尚留余味。然兰谢时即死,
殊不易得,彼地亦甚珍也,惜不知其何名。愚谓此虫可与脉望、鞠通相鼎立,洵称仙品,宜其不易得也。夫虫

《本经》淫羊藿气寒味辛无毒,主阴痿绝伤,茎中痛,利小便,益气力,强志。后人因《别录》羊食而淫

The character for "medicine" (Yao) has the radical "grass," therefore Shennong's book on distinguishing medicines is called *Bencao Jing* (Divine Farmer's Materia Medica), indicating that in compiling materia medica, the grass category should be placed first. There are many types of grasses. Confucius said: "Orchid is the fragrance of kings." Thus, regarding orchids among grasses, it is like the Qilin among beasts or the Fenghuang among birds. Later compilers of materia medica, if they take the sages' views as the standard for compromise, ought naturally to rank the orchid at the head. Orchids with a pure heart (plain white or pale yellow petals without mixed colors) are prized; they can relieve mental depression, dispel turbid pathogens hidden within, help reduce smallpox lesions and facilitate childbirth, clear the spirit, and nourish fluids. Born from the purest Qi of Heaven and Earth, ancients used the metaphor of "breath smelling like an orchid."
Mr. Xiaolan's *Notes* state: In the border regions of Miaotong, when orchids bloom, there are insects that feed on orchid stamens. They resemble centipedes but are green. If caught and placed in a cup with a little salt sprinkled over them, covered, they dissolve into water within moments—clear, bright green, transparent as glass, with the orchid's fragrance overwhelming the senses. Used as a substitute for vinegar, its fragrance permeates the teeth and cheeks, lingering for half a day. However, these insects die when the orchids wither, making them extremely rare and highly valued locally, though their name was unknown. I believe this insect could stand alongside Maiwang and Jutong, truly worthy of being called a celestial product, no wonder it is hard to obtain. Since an insect eating orchids attains immortality, its efficacy on humans is evident. Yet some use Shengtou Cao (Prunella vulgaris) to substitute for it, which is indeed crude!
(Published) Chaoshan's sugarcane fields are contiguous. The insects feeding on sugarcane resemble silkworm pupae but are smaller, taste extremely sweet, have a cool nature, resolve heat toxins, assist in smallpox pustule formation, and their story can be told alongside that of the orchid insect.
Ancient weights and measures were small, and medicinal doses were light, with most taking only a few qian per dose; today it is the opposite, so drug prices have gradually risen, making illness harder to cure, not just because good doctors are rare. Take Ren Shen (Ginseng Radix et Rhizoma) as an example; it has become a daily dietary item for the wealthy. Ren Shen is merely a root. Heaven grows it originally to treat human diseases, not to sustain the lives of the healthy. Because healthy people compete to buy and consume it as a health-preserving substance, it is no wonder its price rises daily. As the price rises, counterfeit goods increase, and those who genuinely need this medicine cannot use it. Is this not wasting useful talent in useless places, leaving us without usable talent when needed? Actually, ancient Ren Shen was slightly cool and bitter, similar in nature and flavor to modern Xi Yang Shen (American Ginseng Radix). Those who deeply understand medical principles might use them interchangeably, rather than sticking rigidly to tradition, silently praising the high price of Ren Shen and bankrupting the poor. If the syndrome indicates severe deficiency, and American Ginseng seems too weak, one may appropriately supplement with Huang Qi (Astragali Radix), Gan Cao (Licorice Root), Gou Qi Zi (Lycium Fruit), and Long Yan Rou (Longan Aril), depending on how skillfully the practitioner directs them. Additionally, there are customs followed blindly without realizing their errors, briefly discussed above.
Gou Qi Zi (Lycium Fruit) tastes purely sweet, is deep red in color, moist in texture, and neutral in nature. *Shengji Zonglu* uses it singly to treat shortness of breath. I believe it specifically nourishes Heart Blood, unmatched by other herbs. When used together with Xuan Shen (Scrophulariae Radix) and Gan Cao (Licorice Root), named Kan Li Dan (Kanli Pill), it can facilitate communication between the Heart and Kidney.
Rou Cong Rong (Cistanche Stem) is warm and moistening, subduing Yang. For patients with Yin deficiency and floating Yang, it can be used as an adjunct in yin-nourishing and heat-clearing prescriptions.
Shi Chang Pu (Acorus Tatarinowii Rhizome) soothes Heart Qi, unblocks Heart Spirit, harmonizes emotions, and strengthens willpower; it is a miraculous herb. However, secular sources claim it "scatters the mind,"不知 who originated this. If true, why did King Wen of Zhou love it yet have many sons and live long? Thus, in clearing and resolving prescriptions, it is used to rely on its ability to clear phlegm-turbidity and protect the "Palace City" (Heart); in nourishing prescriptions, it relies on its ability to disseminate mental knots and connect to spiritual clarity.
*Benjing* states Yin Yang Huo (Epimedii Folium) is cold in nature, pungent in flavor, non-toxic, mainly treating impotence, severe injuries, pain in the penis, promoting urination, augmenting Qi and strength, and strengthening will. Later authors, due to *Bielu*'s claim that "sheep eat it and become lustful," changed it to hot in nature and Yang-assisting, which is erroneous. Sheep's lustfulness is innate, not necessarily caused by eating this herb. Even if eating it increases lust, leading to its name, humans are not sheep; why would eating it cause lust? In my hometown, sheep are fed mulberry leaves in autumn and winter, so the sheep from Hangzhou, Jiaxing, and Huzhou are best for benefiting humans. But mulberry leaves are what silkworms eat to produce silk. If humans eating Yin Yang Huo causes lust, then sheep eating mulberry leaves should turn into silk. Since internal organs differ, one cannot generalize. For instance, Ming Fan (Alumen), silkworms eat it and grow fat, mice eat it and die. This shows drugs have fixed natures, but effects vary with different bodies. I consider sheep as Fire animals, and the herb receives Water Qi. If sheep eating it increases lust, it aligns with the *Neijing* principle of "Yin balanced and Yang secure." Only Ye Shi says: Yin Yang Huo is cold, receiving Water Qi of Tian Dong season, entering Foot Shaoyin Kidney Meridian; pungent, non-toxic, receiving moist Metal flavor of Earth, entering Hand Taiyin Lung Meridian. Descending qi exceeds ascending, belonging to Yin. Yin refers to the sinews. If Water does not control Fire, Heat makes sinews lose rigidity, causing flaccidity. Yin Yang Huo enters Kidney and is cold; cold controls Fire, curing flaccidity. "Severe injury" means Yin exhaustion and Essence damage. Cold benefits Water, pungent moistens; moistening fills Yin Essence. "Penis" refers to the jade organ. Pain is Fire stagnating internally. Heat is cleared with cold, stagnation dispersed with pungency, hence treating penile pain. Urination occurs via Qi transformation; pungent-cold herbs clear Lung Qi, thus promoting urination. Lung governs Qi, Kidney commands Qi; cold benefits Kidney, pungent moistens Lung, thus augmenting Qi and strength. Augmented Qi and strength nourish inner righteousness, thus strengthening will, as Kidney stores Will. This explanation grasps the essence, recorded to clarify confusion. Moreover, Kidney governs bones; for Yin deficiency bone flaccidity, it is also a key herb. The Classic says, "Kidney dislikes dryness, quickly eat pungent to moisten it," referring precisely to this.
(Published) Zou's *Benjing Xushu* also details that Yin Yang Huo does not assist Yang, consistent with *Jieyao*. Differences in body constitution are not only distinct between humans and animals, but also significantly different among humans. *Buyi Lu* records: Xiao from Jiangnan died after eating fragrant mushrooms; Wang died after drinking tea, reviving only after two or three days, with doctors unable to identify the cause. I once saw Wang Zhensheng from Yi County get drunk after eating turtle; Zhao Zixun, a scholar from Renhe, suffered nosebleeds after drinking sugarcane juice; Yang Suyuan from Dingzhou developed fever after eating sea cucumber, requiring Da Huang (Rhei Radix et Rhizoma) purgation to settle. These cannot be measured by constant logic. If food acts this way, how much more so drugs? Practitioners must know that drugs have fixed natures and effects vary by person, distinguishing constitutional differences first.
Sha Shen (Glehniae Radix or Adenophorae Radix) clears Lung. Since Lung belongs to Metal and fears Fire, clearing Fire protects Metal, hence called "tonifying Lung." Lung governs Qi of the whole body; clear Lung Qi ensures proper regulation, irrigating all organs, hence "tonifying Yin of Five Zang." Clear Lung Qi descends smoothly, aiding Qi transformation and excretion, hence lung-clearing herbs promote urination. Yu Shi said, "Those with Lungs have urine; those without Lungs have no urine," seeing through the mechanism.
(Note) Six Fu organs' Qi transformation must rely on the true Qi of their corresponding Zang organs. Ancients treated cases where Lung Qi failed to transform, Bladder stagnant with heat, causing urinary retention, lower abdominal and testicular distension/pain, using large doses of Sha Shen alone, cured after one cup. This demonstrates Lung Qi transformation leading to urination. Later practitioners, instead of saying Sha Shen treats urinary obstruction, claimed it treats hernia, which is wrong. Huang Lusü was amazed that Radish Seed (Lu Bo Zi) alone promoted urination, thinking it strange. Not knowing Radish Seed is the fastest Qi-descending substance; immediate relief indicates the disease was due to Qi closure. Thus, diagnosing requires investigating the cause of disease; then medication achieves divine efficacy, avoiding the error of using static drugs for dynamic diseases.
Jie Geng (Platycodonis Radix) opens Lung Qi knots, disseminates Heart Qi depression; it is an Upper Jiao herb. Opening Lung Qi unblocks Fu Qi, hence also treating abdominal pain and diarrhea; ancients saying it has descending properties within ascending action are correct. However, it is fundamentally an ascending herb. Suitable for Upper Jiao excess syndromes without Lower Jiao pathology; caution required for Lower Jiao Yin deficiency with floating fire; contraindicated if Upper Jiao symptoms originate from Lower Jiao. The ancient "boat and oar" theory misleads most. Light, clear aromatics treat Upper Jiao; calling them boat/oars is superfluous. Heavy, strong flavors treat Lower Jiao; carrying them upward is meaningless. Thus, not only Lower Jiao diseases are contraindicated, but even Upper Jiao diseases require pathogenic blockage in Lung or Qi stagnation in Heart, confined to Yang divisions, before use. For throat/phlegm coughs, only suitable for external Wind-Cold closure; contraindicated for Yin deficiency/internal injury, and even for Fire-Toxin rising requiring clearing/descending.
Chai Hu (Bupleuri Radix) is essential for Zheng Shanghan (Regular Cold Damage), cannot generally treat Warm-Reheat infections; main herb for Shaoyang Malaria, cannot generally treat malaria of other meridians; excellent gynecological herb, cannot generally treat constitutions with Yin deficiency and Yang hyperactivity; users must be prudent.
(Published) Mr. Zhao Juzhai said: During Qianlong reign, my mother accompanied my grandfather in Panyu office, suffering severe illness, cured by foreign doctors. She advised: "This is Liver Yin deficiency constitution; never take Chai Hu in life." Later, at fifty, she went blind, confirming Liver Yin deficiency. Subsequently catching external pathogen, doctor prescribed small dose Chai Hu; upon swallowing, bilateral hypochondriac distension/pain, vertex heat like blazing sun, urgently irrigated with moistening meds, settled after large stool. *Benjing Shuzheng* says well: Chai Hu usage requires constrained Yin Qi failing to allow Yang Qi to reach. If Yin already deficient, Yang lacks foundation and wants to escape, using ascending Yang accelerates death. Thus, for Yuan Qi sinking, Deficient Fire flaming up, and Yin deficiency fever not due to Blood stasis/Qi obstruction causing alternating chills/fever, approaching Chai Hu is like arsenic.
Bai Ji (Bletillae Rhizoma) is very sticky, greatly tonifies Lung, suitable for post-recovery of upper consumption. If Fire-Heat not cleared, do not use early, as its astringent nature may retain pathogens. Its bitterness is too strong; use sweet herbs as assistants. Sweet retains in chest/throat; better to hold in mouth to slowly moisten throat for greater efficacy. Method: Raw Bai Ji finely powdered, Honey pills, size of longan. Hold in mouth before sleep. Or mix with raw Gan Cao powder, form pills with Pear Juice. For prolonged cough with excessive phlegm, add Bai Qian (Centellae Herba), honey pills, hold in mouth; truly a celestial prescription.
(Published) *Guisi Leigao* claims opium addiction damages Lung; Bai Ji powder with Pear Juice paste cures it. Recent additions to *Xiyoulu* are inaccurate. Lung governs exhalation, Kidney governs inhalation; opium smoking affects respiration, seemingly involving Lung. If Lung scorched, Upper Jiao fluids damaged first, this formula fits. However, chronic smokers usually damage Lower Jiao first, resulting in Lower Deficiency/Upper Excess, Fire boiling fluids, smoke's ascending nature causing phlegm accumulation above. Also, Wang Xunchen stated respiration enters Qi Mansion via Trachea, not directly Lung. According to *Shuowen*, KT refers to scars. *Guangyun*: swelling from beating. Modern people call chronic ulcers KT Chuang. Do not confuse with "smoking trigger." "Yin" (trigger/addiction) implies inability to stop after smoking, leading to death. Vulgar writing uses "Yin" (addiction) due to homophone, losing the wooden radical meaning. Cannot arbitrarily assert opium smokers must develop Lung ulcers!
Dan Shen (Salviae Miltiorrhizae Radix) descends and moves Blood, suitable for Heat-stagnation in Blood, hence key herb for regulating menstruation and postpartum. If menstruation comes early, amenorrhea due to Blood deficiency failing to nourish fetus causing instability, or postpartum Blood flow smooth, do not be confused by claims it equals Si Wu Tang, nor abuse it due to "Shen" in name. Even if efficacious like Si Wu Tang, Si Wu Tang treats Blood division diseases, not primarily tonifies Blood; Shiwan clarified this. Regarding "tonifying Heart," it is not like Gou Qi Zi or Long Yan Rou truly tonifying Heart deficiency. Heart stores Spirit and governs Blood; excessive Heart Fire disturbs Spirit. Dan Shen clears Fire in Blood, calming Spirit and stabilizing Will; calm Spirit benefits Heart. Used when Warm-Reheat pathogens enter Ying Division, for this reason. If pathogen in Qi Division and mistakenly used, it draws pathogen into Ying; caution required.
(Note) For moving Blood, use whole root; for entering Heart, remove tips.
Zhi Mu (Anemarrhenae Rhizoma) is bitter and cold, clears Heat in Lung/Stomach Qi Division. Removing Heat prevents fluid consumption, allowing Yin to grow secretly. However, Zhongjing said: "Stomach Qi generates Heat, its Yang becomes severed." Severe Stomach Heat means Yin insufficient to harmonize Yang, fluids dry up, becoming brittle unable to digest food; "Yang severed" means fluid exhaustion. Clearing Heat prevents Yang severance; thus, fluid-saving meds, though called "tonifying Yang." Later generations considered cold-cool herbs disliked by Stomach, earnestly warning against light use, preferring aromatic-dry-warm-tonic herbs. Why? This world of discussing herbs rather than diseases causes sighs towards Yu Shi.
Bai Wei (Cynanchi Atrati Radix) is slightly cool, descends, clears Blood Heat, key herb for gynecology. Suitable for Warm-Reheat pathogens entering Blood Division. Why modern times don't use it in gynecology but view it as ascending-dispersing, indiscriminately prescribing regardless of Qi/Blood location, causing great harm? Ignorance is worst.
Shao Yao (Paeoniae Radix) flavor: *Benjing* says bitter, *Bielu* adds "sour." Sour-bitter induces vomiting/draining, Yin nature, opening-draining product. Zhongjing said: "Taiyin disease, weak pulse, continuous loose stools; if Dahuang/Shao Yao indicated, reduce dose, as weak Stomach Qi easily disturbed." Hence, for dysentery (Zhi Xia), characterized by tenesmus/blockage, it is main herb. Moderns mistake it for astringent, using for deficiency diarrhea, lacking verification. Suitable only for Spleen affected by Liver Wood overacting.
(Published) Zou's *Shuzheng* says: Shao Yao opens Yin knots, Dahuang opens Yang knots. Intestinal dry constipation uses Chengqi formulas; abdominal fullness/pain often uses Shao Yao. If epigastric fullness/pain, Upper Jiao Yang knot, use Xiantong; Shao Yao contraindicated.
Dan Pi (Moutan Cortex) is not hot, but aromatic-pungent. Qi-blood herb in Blood, specifically moving Blood/breaking stasis, hence abortifacient/reducing masses. Claimed hemostatic effect is because removing stasis allows new Blood to settle, not true hemostasis. Suitable for Blood deficiency with Wind-Cold to induce sweating. Contraindicated for non-stasis Heat bleeding, or Blood deficiency without external pathogen. Only in Yin-nourishing agents, Yin meds benefit from its dispersing action without stagnation, gaining cooling effect. Best for Yin deficiency with Heat entering Blood Division causing bloody dysentery. However, aromatic/turbid, easily causes vomiting; weak Stomach patients vomit immediately; materia medica omit this; users beware.
Mai Dong (Ophiopogonis Radix) indications in *Benjing* are all Stomach diseases; *Chongyuan* explains best. Its function is in Heart, cannot be removed. Master of Mai Dong usage is likely Mr. Xiangyan (Ye Tianshi).
(Published) Miao's *Jingshu* knows Mai Dong is Stomach meridian main herb; *Yuyi Cao* began discussing Spleen/Stomach differential treatment; Ye Tianshi expanded this principle, stating Stomach is Yang Earth, prefers sweet-cool, guiding later generations, hence Huixi and Run'an deeply admired.
Yi Mu Cao (Leonuri Herba) specifically travels Blood Division. Women use Blood, hence name "Benefiting Mother," not implying it doesn't treat men. Suitable for Damp-Heat entering Blood Division, or Blood Heat/Stasis diseases. Moderns restricting it to gynecology is limited.
Xia Ku Cao (Prunellae Spica) is slightly pungent-sweet, thus in resolving nodules, also harmonizes Yang/nourishes Yin. Insomnia after blood loss sleeps immediately upon taking, revealing its nature. Aged ones taste sweeter, superior for medicine.
*Cao Hao* in *Benjing* is now Qing Hao (Artemisiae Annuae Herba), purple stems preferred. Specifically resolves Damp-Heat, aromatic, hence miraculous for Damp-Warmth/Epidemic Toxins. Clears latent Heat in Liver/Gallbladder Blood Division, hence divine for women's leukorrhea/gonorrhea, children's epilepsy/spasms/rickets. Materia medica omitted, specially revealed. Taste very bitter; protect weak Stomach Qi.
Xuan Fu Hua (Inulae Flos) moderns use only for descending rebellion, but *Benjing* says tonifies Middle/Descends Qi. Why? Ascending/descending power lies in Middle Qi. Qi ascending when it shouldn't is "Rebellion"; reversing rebellion to smoothness is "Descending." Reversing rebellion relies on Central Pivot rotation; isn't this Middle-tonifying power? Observe its color. I say "Xuan" is rotating Middle Qi ability, "Fu" is Qi descending to smoothness: naming meaning here.
(Published) Recently read Zou's *Shuzheng* citing *Qunfang Pu*: Dew from Xuan Fu Hua tip dripping into soil sprouts new roots, showing vitality's rotational ascending/descending. Expressing as tonifying Middle/Descending Qi is sage's subtle observation. Xue Yipiao case also says Xuan Fu rotates Middle Qi, matching my great-grandfather's discussion. Worldly people say it drains Qi, dare not use on deficient bodies, how contradictory!
He Shou Wu (Polygoni Multiflori Radix) internally regulates Qi/Blood, externally disperses carbuncles, efficacy near Dang Gui, also Qi-blood herb in Blood. Dang Gui is aromatic-piercing, treats Wind-Cold in Blood Division; He Shou Wu is non-aromatic, treats Wind-Heat in Blood Division, differing. Both key for gynecology/surgery, treat deficiency malaria, lubricate Large Intestine. No strong tonifying power; ancients said replace Shu Di Huang, actually incorrect. An'an Mr. said Shu Di Huang and He Shou Wu both are Jun (Emperor) herbs, cannot use together in formula, especially laughable. Whether herb is Jun/Chen depends on syndrome/formulation; seeing syndrome, using herb makes it Jun. Understand this, any materia medica herb can be Jun. Book says: Appoint officials only by virtue/talent; wise rulers judge by merit, not status. Herbs/minerals are medicinal materials, judged by efficacy, not price/purity. Good doctors/herbalists share merit, recognizing talent/appropriateness. Medical Dao connects to Governance Dao.
Gua Lou Gen (Trichosanthis Radix), alias Tian Hua Fen, cool nature, sweet taste, generates fluids, stops thirst, transforms Dry-Phlegm. Zhongjing clearly said: Thirst -> remove Ban Xia, add Gua Lou Gen. Evidence Ban Xia transforms Wet-Phlegm, Tian Hua Fen transforms Dry-Phlegm. Later readers skimmed, missed meaning, paired Bei Mu with Ban Xia, inappropriate.
Gua Lou Shi (Trichosanthis Fructus), alias Tian Gua, hence root named Tian Gua Fen. Later corrupted "Gua" to "Hua," long established, unchangeable. Gua Lou Shi moistens dryness/resolves knots, sweeps Heat/cleanses Phlegm, known by all, but unaware of unique merits soothing Liver Depression/moistening Liver Dryness/calming Liver Rebellion/relieving Liver Cramps. Yuheng Mr. explained best. Modern pharmacies name this Gua Lou, using Tu Gua Gen seeds as Gua Lou; users must examine carefully. Tu Gua alias Wang Gua, i.e., *Yueling* Mengxia Wang Gua Sheng, not vegetable garden Huang Gua. Vegetable garden Huang Gua alias Hu Gua; *Suiyuan Shidan* writing "Wang Gua" is error.
