咸温小毒。取未交雄蛾，纸封焙干，拌椒密藏则不蛀。
《本经》主心腹邪气，起阴痿，益精气，强志生子，好颜色，补中轻身。
发明 蚕之性禀淫火，力专助阳。其子在腊月中非以重盐盐透，水渍曝干，则茧不能缫
丝，出子之后非桑不食。《本经》主心腹邪气，皆桑之余力，犹僵蚕之治风痰，蚕茧之疗痈
肿，蚕沙之去风湿耳。其起阴痿，益精气，强志，生子，即《别录》之益精气，强阴道，交
精不倦，亦能止精，若合符节。好颜色，令人面色好之互辞。补中轻身者，以其善补真阳，
阳主轻捷故也。详参经旨洵为原蚕，主治无疑，奈何集《本草》者误列樗鸡之下，敢力正之
。
咸平无毒。色白者良，入药惟取直者，为雄，去黑口及丝，炒用。
《本经》主小儿惊痫、夜啼，去三虫，灭黑 ，令人面色好，男子阴痒病。
发明 僵蚕，蚕之病风者也。功专祛风化痰，得乎桑之力也。《本经》治惊痫，取其散
风痰之力也。去三虫，灭黑 ，男子阴痒，取其涤除浸淫之湿，三虫亦湿热之蠹也。凡咽喉
肿痛及喉痹用此，下咽立愈。其治风痰，结核，头风，皮肤风疹，丹毒作痒，疳蚀，金疮疔
肿，风疾，皆取散结化痰之义。
【原蚕蛾】
味咸，性温，有小毒。选取尚未与雄蛾交配的雌蛾，用纸包裹后焙干，拌入花椒密封贮藏，则不会生虫蛀蚀。
《神农本草经》记载其主治心腹部的邪气，治疗阳痿不起，补益精气，增强意志并利于生育，使面色红润光泽，补益中焦并使身体轻健。
发明：蚕的本性禀受淫火之气，药力专门辅助阳气。它的子（蚕卵）在腊月间，如果不以重盐腌透，用水浸泡后晒干，茧就不能缫丝；出子之后，非桑叶不吃。《本经》所说的主治心腹邪气，都是桑叶的剩余功效，就像僵蚕治疗风痰、蚕茧治疗痈肿、蚕沙去除风湿一样。至于起阴痿、益精气、强志、生子，即《名医别录》所说的益精气、强阴道、性交时精液不疲倦，也能固精止泄，两者如符节相合般一致。“好颜色”与“令人面色好”是互文见义的说法。“补中轻身”，是因为它能善于补益真阳，阳气主司轻捷的缘故。详细参究经旨，确认为原蚕蛾的主治无疑，为何汇集《本草》的人错误地将其列在樗鸡之下？我敢于极力纠正这一错误。
【白僵蚕】
味甘，性平，无毒。色泽白色的品质优良，入药只取直行的个体，视为雄性，去掉黑色的口器及丝状物，炒制后使用。
《神农本草经》记载其主治小儿惊痫、夜间啼哭，驱除三虫，消除黑斑，使人面色红润，治疗男子阴部瘙痒病。
发明：僵蚕是患风病的蚕。其功效专门在于祛风化痰，得益于桑叶的力量。《本经》治疗惊痫，是利用其疏散风痰的力量。驱除三虫、消除黑斑、治疗男子阴痒，是利用其涤除浸淫之湿气的功效，三虫也是湿热所生的蠹虫。凡是咽喉肿痛及喉痹使用此药，咽下后立即痊愈。它治疗风痰、结核、头风、皮肤风疹、丹毒作痒、疳蚀、金疮疔肿、风疾等，都是取其散结化痰的意义。
【蚕茧】
味甘，性温，无毒。
[Original Silkworm Moth]
Salty, warm, slightly toxic. Select female moths that have not yet mated with males, wrap them in paper, bake until dry, mix with Sichuan pepper, and store in a sealed container to prevent insect infestation.
The *Shennong Bencao Jing* (Divine Farmer's Materia Medica) states that it treats evil qi in the heart and abdomen, cures impotence, benefits essence and qi, strengthens willpower and facilitates procreation, improves complexion, tonifies the middle jiao, and makes the body light and agile.
Innovation: The nature of silkworms is endowed with yin-fire, and its power specifically assists yang. Its offspring (eggs), during the twelfth lunar month, if not thoroughly salted with heavy salt, soaked in water, and dried in the sun, cannot be reeled into silk; after hatching, they feed exclusively on mulberry leaves. The treatment of evil qi in the heart and abdomen mentioned in the *Bencao Jing* are residual effects of the mulberry leaf, just as Stiff Silkworm (Baijiangcan) treats wind-phlegm, Silkworm Cocoon (Canjian) treats carbuncles and swellings, and Silkworm Excrement (Cansha) dispels wind-dampness. As for curing impotence, benefiting essence and qi, strengthening willpower, and facilitating procreation, this corresponds exactly to the *Mingyi Bielu* (Record of Famous Physicians) stating that it benefits essence and qi, strengthens the yin vessel, prevents seminal emission during intercourse, and can also stop leakage. These accounts match like tally marks. "Improves complexion" and "makes one's face beautiful" are mutually explanatory phrases. "Tonifies the middle and makes the body light" occurs because it effectively tonifies true yang; since yang governs agility, the body feels light. A detailed examination of the canonical principles confirms that the therapeutic indications belong undoubtedly to the original silkworm moth. Why did compilers of materia medica erroneously list it under *Chuji* (Swallowtail Moth)? I dare to vigorously correct this error.
[Stiff Silkworm / Bai Jiang Can]
Sweet, neutral, non-toxic. Those with a white color are superior. For medicinal use, only straight ones are selected, considered male. Remove the black mouthparts and silk, stir-fry before use.
The *Shennong Bencao Jing* states that it treats pediatric convulsions and epilepsy, night crying, eliminates three parasites, removes dark spots, improves complexion, and treats pruritus of the male genitals.
Innovation: Stiff silkworm is a silkworm afflicted by wind. Its function specializes in dispelling wind and resolving phlegm, deriving from the power of the mulberry leaf. The *Bencao Jing* treats convulsions and epilepsy by utilizing its ability to scatter wind-phlegm. Eliminating three parasites, removing dark spots, and treating genital pruritus utilize its ability to cleanse dampness that oozes and spreads; the three parasites are also pests generated by damp-heat. Whenever used for sore throat swelling and pain or obstruction of the throat, immediate relief follows upon swallowing. Its treatment of wind-phlegm, scrofula, headache due to wind, skin urticaria, erysipelas with itching, gangrenous sores, traumatic wounds with carbuncle swellings, and wind diseases all rely on the principle of scattering nodules and resolving phlegm.
[Silkworm Cocoon / Can Jian]
Sweet, warm, non-toxic.
Innovation: Silkworm cocoon treats unruptured carbuncles and swellings; when calcined to ash and taken with wine, it ruptures the next day. Decoction treats diabetes mellitus (xiao ke); the water used for reeling silk and the decoction of silk floss have identical functions.
