【性味】味道咸，性质温、微寒，无毒。主治消渴病，清除内热，益气调和中焦。又有说法称：食用后令人产生多热感，是五谷中生长周期最长的。（蜂蜜作为其引经药/使药。）
陶隐居说：现在的稞麦，又名牟麦（音同“牟”），形状像大麦，只是皮较薄而已。《唐本草》注解说：大麦产于关中地区，即青稞。治疗腹胀满，具有下气及补益腰肾的作用。长期服用非常适宜于人，煮熟则有益于人，带生吃则寒冷伤身。陈士良说：大麦，能补益虚弱，强壮血脉，改善面色，充实五脏，转化谷食。长期食用使人肌肤肥白滑润。做成面粉比小麦更好，没有燥热之弊。又有说法称，它微暖，长期食用会耗损肾气，不可多吃。日华子说：麦麸，能温中下气，开胃，止霍乱，除烦闷，消痰，破除症结，能促进分娩和堕胎。
《图经本草》在小麦条目下有详细记载。
陈藏器说：不扰动风气，调和脾胃止泄泻，使人肥壮健壮。大麦、牟麦，《神农本草经》前后两次出现。苏颂说：青稞就是大麦，《本经》中有相关条目，粳米与稻米的比例是一比二，也如同大麦与牟麦的关系。苏颂说：稻是谷物的通名，那么牟麦就是麦类的通名。《本经》在米麦条中重复列出皮壳两样东西，仅仅是因为有壳和无壳的区别。苏颂说：大麦是青稞，牟麦是大麦。如此则与米注不同，自相矛盾。我认为大麦是指去皮的麦米，牟麦是指带壳的麦谷，这与青稞种子不同。青稞类似大麦，天生皮肉分离。秦陇以西地区种植它，现在的人将其当作本地产的麦米黍类，无法分辨。
《圣惠方》：治疗妊娠欲堕胎。用麦麸二两，水一盏半，煎至一盏，分三次温服。《外台秘要》：治疗妊娠患病需堕胎的方子：用麦麸一升，加蜂蜜一升，服用后即下行，神效。孙真人：麦芒入眼，煮大麦汁洗眼。治疗产后腹中鼓胀不通转，气急，坐卧不安，供奉辅太初与崔家方：用麦麸煮良久，可使气机通转。崔郎中说神效。
《伤寒类要》：治疗各种黄疸，捣取麦苗汁服用。又一方：用蠼螋尿涂敷。
《衍义》说：大麦，性平、凉。有人患缠喉风，饮食不能下咽，将此面制成稀糊，令其吞咽，既滑腻容易下咽，以助胃气。三伏期间，朝廷制作饴糖，用以赏赐臣下，制作成饧。
[Properties and Flavors] Salty in taste, warm and slightly cold in nature, non-toxic. It primarily treats thirst-quenching disease (Xiao Ke), clears internal heat, benefits Qi, and harmonizes the middle jiao. Another view states: it causes excessive heat in the body and is the longest-growing among the five grains. (Honey acts as its guiding herb/enforcer.)
Tao Hongjing stated: The current Kemu (裸麦/Spelt), also known as Moumai (牟麦, pronounced "Mou"), resembles Damai (Barley) but has a thinner husk. The annotation of *Tang Bencao* notes: Damai originates from the Guanzhong region, which is Qingke (Highland Barley). It treats abdominal distension and fullness, directs Qi downward, and benefits the waist and kidneys. Long-term consumption is very suitable for humans; when cooked thoroughly, it benefits the body, but when consumed raw, its cold nature damages the body. Chen Shiliang stated: Damai supplements deficiency and weakness, strengthens blood vessels, improves complexion, solidifies the five zang organs, and aids in the digestion of grains. Long-term consumption makes the skin fat, white, and smooth. Made into flour, it is superior to Xiaomai (Wheat) and lacks燥热 (dry-heat) properties. Another view states it is slightly warm; long-term consumption consumes Kidney Qi, so it should not be eaten in excess. Ri Huazi stated: Maifan (Bran/Husk of wheat/barley), warms the middle and directs Qi downward, opens the appetite, stops cholera-like vomiting and diarrhea, relieves irritability, resolves phlegm, breaks up mass formations, and can induce labor or abort fetuses.
*Tujing Bencao* provides detailed records under the entry for Xiaomai (Wheat).
Chen Cangqi stated: It does not disturb wind-qi, harmonizes the middle and stops diarrhea, making one fat and robust. Damai and Moumai appear twice in *Shennong Bencao Jing*. Su Song stated: Qingke is Damai. There is an entry in *Bencao Jing*; the ratio of Jingmi (Japonica Rice) to Daomi (Indica Rice) is one to two, similar to the relationship between Damai and Moumai. Su Song stated: Dao is the general term for grain, thus Moumai is the general term for Mai (barley/wheat). The repetition of husk and grain in *Bencao Jing* under the rice and barley section is merely due to the distinction between hulled and unhulled grains. Su Song stated: Damai is Qingke, and Moumai is Damai. This contradicts the previous note on rice. I believe Damai refers to the dehulled grain, while Moumai refers to the whole grain with husk, which differs from Qingke seeds. Qingke resembles Damai but naturally has the husk and kernel separated. It is cultivated west of Qin and Long. Currently, people mistake it for local grain varieties like millet and cannot distinguish them.
*Shenghui Fang*: For treating pregnancy where abortion is desired. Use 2 liang of Maifan (Bran), add 1.5 cups of water, decoct until 1 cup remains, divide into three warm doses. *Waitai Miyao*: Formula for inducing abortion due to illness during pregnancy: Use 1 sheng of Maifan, mix with 1 sheng of honey, take orally, and the fetus will pass down immediately; this is miraculous. Sun Simiao: If barley awn enters the eye, decoct Damai to wash the eye. To treat postpartum abdominal distension and obstruction, shortness of breath, and restlessness: Gongfeng Fu Taichu and the Cui Family Formula: Decoct Maifan for a long time to restore bowel movement and Qi flow. Dr. Cui claimed it was miraculous.
*Shanghan Leiyao*: To treat various types of jaundice, crush the seedlings and extract juice for oral administration. Another formula: Apply urine from the earwig (Qusu) externally.
*Yanyi* stated: Damai has neutral and cool properties. A person suffering from Chanhou Feng (Peritonsillar abscess/Quinsy) could not swallow food. By making a thin paste from this flour and having them swallow it, the slippery texture facilitates swallowing and assists Stomach Qi. During the Sanfu days (Dog Days), the court produced Yitang (Maltose/Syrup) to bestow upon officials, made into thick syrup.
