畏、恶、反、使，与生姜同。
【白话翻译】干姜的“畏、恶、反、使”（中药配伍禁忌及辅助关系）与生姜相同。
辛，热。入手少阴、足太阴经气分。生则逐寒邪而发散，熟则除胃冷而守中。开脏腑，通肢节，逐沉寒，散结气。治停痰宿食，呕吐泻痢，霍乱转筋，寒湿诸痛，痞满症积，阴寒诸毒，扑损瘀血。得北味，摄膀胱之气。配良姜，温脾以祛疟。佐人参，助阳以复阴。合附子，回肾中之阳。
【白话翻译】味道辛，性热。归入手少阴心经和足太阴脾经的气分。生用能驱逐寒邪并使其发散，炒熟后能去除胃部寒冷并固守中焦。它能开通脏腑，疏通肢体关节，驱逐深层的寒邪，消散郁结的气机。用于治疗停滞的痰饮和隔夜的饮食，呕吐、腹泻和痢疾，霍乱引起的肌肉痉挛，寒湿导致的各种疼痛，痞块胀满及积聚病症，阴寒性质的各种毒疮，以及跌打损伤导致的瘀血。若与五味子（北味）配合，可收敛膀胱之气；若与高良姜配伍，可温暖脾胃以祛除疟疾；若与人参佐使，可辅助阳气以恢复阴液；若与附子合用，可挽回肾脏中的阳气。
母姜去皮晒干者为干姜，白净结实，又曰白姜。凡入药并宜炮用。入止泻药，煨用。入温中药，泡用。入止血药，炒炭用。孕妇服之，令胎内消。气虚者服之，伤元。阴虚内热多汗者禁用。
【白话翻译】母姜（老姜）去皮晒干制成的称为干姜，色泽白净且质地坚实，又称白姜。凡是入药都适宜经过炮制使用。用于止泻方剂时，采用煨制法；用于温中暖胃方剂时，采用浸泡或微炒法；用于止血方剂时，需炒成炭使用。孕妇服用会导致胎儿在腹中消亡。气虚者服用会损伤元气。阴虚伴有内热且多汗者严禁服用。
服干姜以治中者必僭上，宜大枣补之，甘草缓之。
【白话翻译】服用干姜来治疗中焦疾病时，其药性必然会上冲过头，适宜用大枣来补益，用甘草来缓和其烈性。
炮姜即干姜水净炙黄者
【白话翻译】炮姜是指将干姜用水洗净后，文火炙烤至黄色的制品。
辛、苦、热。入足太阴经血分，守而不走。燥脾胃之寒湿，除脐腹之寒痞，暖心气，温肝经。（心本热，肝本温，虚则寒冷。）能去恶生新，使阳生阴长，故吐衄下血，有阴无阳者宜之。佐当归，治血痢。（中气温，血自归经。）入四物，治产热。（木土得养而热退。）
【白话翻译】味道辛、苦，性热。归入足太阴脾经的血分，性质守中而不向外发散。它能燥化脾胃的寒湿，消除脐腹部的寒性痞块，温暖心气，温煦肝经。（心脏本性属热，肝脏本性属温，若出现虚证则会感到寒冷。）它能去除败血、生成新血，促使阳气生长、阴血滋养，因此对于吐血、鼻出血及下部出血，属于阴盛阳衰（有阴无阳）证候者适宜使用。若佐以当归，可治疗血痢。（因为中焦温暖，血液自然回归经脉。）若加入四物汤中，可治疗产后发热。（因为肝木与脾土得到滋养，发热自然消退。）
止血，炒炭。忌用同干姜。
【白话翻译】用于止血时，需炒成炭使用。注意：此处指炮姜在特定语境下的用法差异，或提示某些情况下不宜简单混同，原文意指炮姜作为止血药时需炒炭，且需注意其与干姜在功效侧重上的区别，避免误用。*注：原文“忌用同干姜”在此处语境略显突兀，通常指炮姜与干姜虽同源但功效不同，不可随意替代，特别是止血时需特指炮姜炭。*
痢亦有因热而下血者，产后多因血虚而生热者，若概用炮姜治之，益增内热，而血不止，愈烁其阴，而热更甚。急宜凉补养其血，以去其热，炮姜非所治也。
【白话翻译】痢疾也有因热邪导致下血的，产后发热多因血虚而生内热。如果一概使用炮姜治疗，只会增加内热，导致出血不止，进一步灼伤阴液，使热势更加严重。此时应当紧急使用凉补之法滋养血液，以清除热邪，炮姜并不适用于此类情况。
辛，温。入足阳明经。利肠胃，通血脉，除膈中臭气。泄泻者禁用。
【白话翻译】（此段描述蒿菜/青蒿类植物，虽标题为蒿菜，但内容似泛指某辛温入阳明经之物，结合《得配本草》上下文，此处可能指代另一种药材或蒿菜的某种特性，但根据原文结构，最后一段独立存在）味道辛，性温。归入足阳明胃经。能通利肠胃，疏通血脉，消除胸膈间的浊臭之气。腹泻者严禁服用。
Fear, aversion, incompatibility, and assistance (Wu, E, Fan, Shi - the eight principles of compatibility) are the same as those of Shengjiang (Fresh Ginger).
Pungent, Hot. Enters the Qi level of the Hand Shaoyin (Heart) and Foot Taiyin (Spleen) meridians. When raw, it expels cold pathogens and promotes dispersion; when cooked, it eliminates stomach cold and stabilizes the Middle Jiao. It opens the Zang-Fu organs, unblocks the limbs and joints, drives out deep-seated cold, and dissipates stagnant Qi. It treats retained phlegm and old food stagnation, vomiting, diarrhea, and dysentery, cholera with muscle cramps, various pains due to cold-dampness, fullness and masses, various poisons due to Yin-cold, and traumatic blood stasis. Combined with Beiwei (Schisandrae Fructus), it secures the Qi of the Bladder. Paired with Liangjiang (Galangal Rhizome), it warms the Spleen to dispel malaria. Assisted by Renshen (Ginseng Radix et Rhizoma), it aids Yang to restore Yin. Combined with Fuzi (Aconiti Lateralis Radix Praeparata), it restores the Yang within the Kidney.
The mother ginger peeled and sun-dried is called Ganjiang (Dried Ginger), which is white, clean, and solid, also known as Baijiang (White Ginger). For medicinal use, it should always be processed. For anti-diarrheal formulas, it is used after being baked/wrapped in flour (Wei). For warming-middle formulas, it is used after soaking/light frying (Pao). For hemostatic formulas, it is used charred (Chao Tan). If taken by pregnant women, it causes the fetus to abort. If taken by those with Qi deficiency, it damages Yuan Qi (Original Qi). It is contraindicated for those with Yin deficiency and internal heat accompanied by excessive sweating.
When taking Ganjiang to treat the Middle Jiao, its action must inevitably overreach upwards; therefore, Dazao (Jujubae Fructus) should be added to tonify, and Gancao (Glycyrrhizae Radix et Rhizoma) to moderate its intensity.
Paojiang (Prepared Ginger) refers to Ganjiang that has been washed with water and stir-fried until yellow.
Pungent, Bitter, Hot. Enters the Blood level of the Foot Taiyin (Spleen) meridian. It stays in place rather than moving outward. It dries cold-dampness of the Spleen and Stomach, eliminates coldfulness in the umbilical and abdominal regions, warms Heart Qi, and warms the Liver meridian. (The Heart is naturally hot, the Liver is naturally warm; deficiency leads to cold.) It can eliminate evil blood and generate new blood, promoting the growth of Yang and Yin. Therefore, it is suitable for cases of vomiting blood, epistaxis, and lower bleeding where there is Yin without Yang. Assisted by Danggui (Angelicae Sinensis Radix), it treats bloody dysentery. (When the Middle Jiao is warm, blood returns to its vessels.) Added to Siwu Tang (Four Substances Decoction), it treats postpartum fever. (When Wood and Earth are nourished, the fever subsides.)
For hemostasis, it is used charred. Caution: Do not use interchangeably with Ganjiang indiscriminately.
Dysentery may also involve bleeding due to heat, and postpartum conditions often involve heat generated from Blood deficiency. If Paojiang is generally used to treat these, it will further increase internal heat, causing bleeding to persist, burning up Yin more severely, and making the heat even worse. Urgent treatment should employ cooling tonification to nourish the Blood and clear the heat; Paojiang is not indicated for such cases.
Pungent, Warm. Enters the Foot Yangming (Stomach) meridian. It benefits the intestines and stomach, unblocks the blood vessels, and removes foul odor from the chest diaphragm. It is contraindicated for those with diarrhea.
