禀天地阳和之气以生，味辛，气温，无毒。入足太阴、阳明、少阴、厥阴。也入手
太阴阳明厥阴可升可降，降多于升，阳也。辛能散能润，温能和畅通达，故治一切虚寒
凝结气滞。
缩砂仁，辛温香窜，补肺益肾，和胃醒脾，快气调中，通行结滞。除霍乱恶心，却
腹痛安胎，温脾胃下气消食；治冷泻赤白，及休息痢，上气奔豚，鬼疰邪疰，转筋吐
泻，胃气壅滞，丹田虚寒，能温脾胃，困乏能醒。然未免香燥走窜，孕妇气虚者，多服
反致难产，不可不知。若肺热咳嗽，气虚肿满，火热腹痛，血热胎动，皆宜禁用。
主治（痘疹合参） 去壳炒研用。若治孕妇安胎者，宜带壳炒研。凡痘腹中虚寒作
痛，并脾胃气结滞不散作闷，不思饮食，虚冷泻痢呕吐，消食健胃安胎，皆所必用，但
气味香燥，不利于灌脓之时，及咳嗽喉痛音哑之症，均宜切忌。倘不得已投于阴虚有火
之人，宜盐汤浸炒用之。
禀清和芬烈之气，味辛气温，无毒。气浓味薄，浮而升，阳也。入手足太阴，亦入
足阳明经，故治风水毒肿，恶气内侵，霍乱腹痛，温中快气之要药。
藿香拣去枝梗入剂，专调脾肺二经，理霍乱，止呕吐，开胃口，进饮食，治口臭难
闻，消风水延肿。以馨香之正气。能辟诸邪；以性味之辛温，通疗诸呕。但肾热胃弱
作呕者，非其所宜。若受寒受秽腹痛者，实为要药。
主治（痘疹合参） 开胃温中进食，止呕吐去恶寒。
按∶《楞严经》谓之兜娄婆香。禀清和芳烈之气，为脾肺达气要药。若阴虚火旺，
胃热作呕者，戒之。
（缩砂仁）禀受天地阳和之气而生，味道辛，性温，无毒。归入足太阴脾经、足阳明胃经、足少阴肾经、足厥阴肝经；也入手太阴肺经、手阳明大肠经、手厥阴心包经。其药性可升可降，以降为主，属阳。辛味能发散也能润燥，温性能调和、通畅、通达，因此能治疗一切因虚寒导致的凝结和气机阻滞。
缩砂仁，气味辛温且芳香走窜，能补肺益肾，和胃醒脾，行气调中，通行郁结阻滞。能消除霍乱引起的恶心，缓解腹痛并安胎，温暖脾胃、下气消食；治疗冷泻、赤白痢疾以及休息痢，还有上气奔豚、鬼疰邪疰（指具有传染性的慢性消耗性疾病）、转筋吐泻、胃气壅滞、丹田虚寒等症状，能温暖脾胃，使困乏状态得以清醒。然而，它终究带有香燥走窜之性，孕妇若气虚，多服反而可能导致难产，这一点不可不知。如果是肺热咳嗽、气虚导致的肿满、火热腹痛、血热胎动等情况，都应当禁用。
主治（结合痘疹病症参考）：去壳后炒制研碎使用。如果用于治疗孕妇安胎，宜带壳炒制研碎。凡是痘疮患者腹中因虚寒而作痛，以及脾胃气机结滞不散导致胸闷、不思饮食、虚冷泻痢呕吐等症，都需要用到此药来消食健胃安胎。但因其气味香燥，在痘疮灌浆时期，以及出现咳嗽、喉痛、音哑等症状时，都应严格禁忌。如果不得已要用于阴虚有火之人，宜用盐汤浸泡后炒制使用。
（藿香）禀受清和芬烈之气，味道辛，性温，无毒。气浓味薄，药势浮而上升，属阳。归入手太阴肺经、手阳明大肠经、足太阴脾经，也归入足阳明胃经，因此是治疗风水毒肿、恶气内侵、霍乱腹痛的温中快气的重要药物。
藿香需拣去枝梗入药，专门调理脾肺二经，治理霍乱，止住呕吐，打开胃口，促进饮食，治疗口臭难闻，消除风水引起的肿胀。凭借馨香的正气，能驱避各种邪气；凭借辛温的性味，普遍治疗各种呕吐。但是，对于肾热胃弱引起的呕吐，并不适宜。如果是受寒或受秽浊之气导致的腹痛，确实是关键药物。
(Sha Ren, Amomi Fructus Rotundus) Born from the Yang and harmonious Qi of Heaven and Earth, it tastes pungent, is warm in nature, and is non-toxic. It enters the Foot Taiyin (Spleen), Foot Yangming (Stomach), Foot Shaoyin (Kidney), and Foot Jueyin (Liver) meridians; it also enters the Hand Taiyin (Lung), Hand Yangming (Large Intestine), and Hand Jueyin (Pericardium) meridians. Its action can ascend and descend, with descending being predominant, thus belonging to Yang. Pungency can disperse and moisten, while warmth can harmonize, unblock, and penetrate; therefore, it treats all conditions of condensation and Qi stagnation caused by deficiency-cold.
Sha Ren has a pungent, warm, and aromatic penetrating quality. It tonifies the Lung and benefits the Kidney, harmonizes the Stomach and awakens the Spleen, promotes Qi movement and regulates the Middle Jiao, and unblocks stagnation. It eliminates nausea associated with Huoluan (Cholera-like syndrome), relieves abdominal pain and calms the fetus, warms the Spleen and Stomach, directs Qi downward, and aids digestion. It treats cold diarrhea, dysentery with red and white discharge, as well as intermittent dysentery, Shangqi Bentun (Rising Qi resembling a pig rushing up), Guizhu Xiezhu (ghostly infections characterized by chronic wasting), muscle spasms with vomiting and diarrhea, Stomach Qi obstruction, and Xuhan of the Dantian. It warms the Spleen and Stomach and alleviates fatigue. However, its nature is inevitably aromatic, dry, and penetrating. Pregnant women with Qi deficiency should avoid excessive use, as it may lead to difficult labor; this must be known. In cases of Lung-heat cough, fullness and swelling due to Qi deficiency, abdominal pain due to fire-heat, or fetal restlessness due to blood-heat, it is strictly contraindicated.
Main Indications (Reference for Smallpox and Measles): Use the peeled seed, stir-fried and ground. If used for calming the fetus in pregnancy, use the shell-on seed, stir-fried and ground. It is essential for treating abdominal pain due to deficiency-cold in smallpox/measles patients, chest oppression due to stagnant Qi in the Spleen and Stomach, loss of appetite, vomiting and diarrhea due to deficiency-cold, and for aiding digestion, strengthening the Stomach, and calming the fetus. However, due to its aromatic and drying nature, it should be strictly avoided during the pustule-filling stage of smallpox/measles and in conditions involving cough, sore throat, and hoarseness. If unavoidable use is required for individuals with Yin deficiency and fire, it should be soaked in salt water and then stir-fried before use.
(Huo Xiang, Patchouli Herba) Born from clear, harmonious, and fragrant-aromatic Qi, it tastes pungent, is warm in nature, and is non-toxic. Its Qi is strong while its taste is light; it floats and ascends, thus belonging to Yang. It enters the Hand Taiyin (Lung), Hand Yangming (Large Intestine), Foot Taiyin (Spleen), and Foot Yangming (Stomach) meridians. Therefore, it is a key herb for warming the Middle Jiao, promoting Qi movement, and treating Fengshui Du Zhong (wind-water toxic swelling), internal invasion of foul Qi, and abdominal pain associated with Huoluan.
Huo Xiang should have its branches and stems removed before decoction. It specifically regulates the Spleen and Lung meridians, treats Huoluan, stops vomiting, opens the appetite, promotes food intake, treats offensive breath, and resolves wind-water swelling. Its fragrant righteous Qi repels various pathogens; its pungent and warm nature generally treats various types of vomiting. However, it is not suitable for vomiting caused by Kidney heat and weak Stomach function. For abdominal pain caused by cold or filth invasion, it is indeed a crucial herb.
Main Indications (Reference for Smallpox and Measles): Opens the stomach, warms the Middle Jiao to promote eating, stops vomiting, and dispels evil cold.
Commentary: Known as Dou Lou Po Xiang in the *Shurangama Sutra*. Born from clear, harmonious, and fragrant-aromatic Qi, it is a key herb for venting Qi in the Spleen and Lung. It should be prohibited for those with Yin deficiency and hyperactive fire, or vomiting caused by Stomach heat.
