(Ricini Semen) has the effects of purging, unblocking orifices and extracting toxins, and expelling tangible stagnations.
Pungent, sweet, and hot in nature. Its action is good at astringing and also good at moving. It can open various orifices and collaterals. Treats headache caused by wind pathogen (when pain is unbearable, mix Frankincense [Boswelliae Resina] and Ricini Semen in equal parts, pound into a paste, apply to the Taiyang acupoint on the affected side to release the exterior and vent qi, which is very effective). Treats facial paralysis with deviation of mouth and eyes (pound into a paste, apply to the healthy side if the face deviates to the left, or to the left side if it deviates to the right, which will correct the condition). Treats nasal obstruction and deafness (pound into a paste, wrap in cotton, insert into nose or ear). Treats throat bi syndrome and swollen tongue (grind Ricini Semen into oil, make paper wicks, burn them to smoke the affected area). It can expel tangible stagnations. Treats foreign bodies like needles embedded in flesh (pound and apply to the wound, check frequently; remove the medicine immediately after extracting the needle, lest it pulls out healthy flesh). Treats fish or wood bones stuck in the throat (mix with twice the amount of Gypsum Fibrosum [Shuijing Shi], grind evenly, place a pinch on the root of the tongue, hold and swallow, the sensation of obstruction will naturally disappear). It can reduce swelling, promote pus discharge, and extract toxins. Applied externally for scrofula and malignant sores, and all kinds of swellings and toxic conditions (achieves remarkable results. Oil of Pelican can guide medicinal qi inward, while Ricinus oil can draw out toxic vapors outward, thus many plasters use it extensively). The flavor and aroma are quite similar to Crotonis Fructus (Badou). Internal use should not be taken lightly. It resembles a cattle tick, yellowish-brown with spots. Boil in salt water, peel, and grind. Or extract the oil. Avoid iron. (Gujin Luyan records: For scalds and burns, mix Ricini Semen and Arcae Concha powder in equal parts; for scalds, mix with oil and apply; for burns, mix with water and apply, which is effective; for yellowish skin that does not turn black, fry Ricini Semen in sesame oil until charred, filter the dregs, and brush frequently after three days, which is effective; for tinea pedis causing pain, grind seven Ricini Semens into a paste, mix with Suhexiang Wan, and apply to the sole of the foot, pain stops immediately.)

(Guanzhong / Cyrtomii Rhizoma) has the effects of purging heat and resolving toxicity.
Bitter, slightly cold. It can resolve toxicity from evil heat. Treats metrorrhagia and metrostaxis, stranguria, leukorrhea, postpartum blood and qi distension and pain, traumatic injuries with bleeding, and epistaxis. Breaks up masses and accumulations, promotes eruption of macules and pustules. Dissolves bone obstructions (has the ability to soften hardness). Kills various parasites. Toxic yet capable of resolving toxicity; removes stasis yet generates new blood. Also known as Guanzhong. Is it because the pronunciation is similar? Or because it possesses an aura of hegemony? The rhizome resembles Cibotii Rhizoma (Gouji) but is larger. The juice can restrain Sanhuang (Coptidis Rhizoma, Scutellariae Radix, Phellodendri Cortex), dissolve five metals, subdue Stalactitum (Zhongru Shi), condense cinnabar and control mercury. Resolves toxicity and softens hardness (soak in a water vat; drinking this water daily can ward off seasonal epidemics).
