陶隐居说：荏的形态像苏（紫苏），植株高大硕壮，颜色偏白，香气不浓。将其种子研磨后，掺入米中煮粥，非常肥美，能降气，有补益作用。
东方人称呼它为“KT”（音同“鱼”），因为它的字形与“苏”相似，只是去掉了“禾”字旁。压榨其种子制成油，经过日晒煎炼，就是现在用于涂饰丝织品和调和漆料所使用的油，服食辟谷时也使用它，称为重油。《唐本草》注解说：《名医别录》记载荏叶，人们经常生吃，所以认为其种子的功效不如苏（紫苏）。
如今考察陈藏器的《本草拾遗》记载：荏叶，捣碎后外敷可治疗虫咬伤及男子阴部肿胀。江东地区用荏子榨油，北方地区用大麻子榨油，这两种油都可用于涂饰物品，如果用来调和漆料，荏油更为坚固。臣禹锡等人谨按孟诜的说法：荏子，其叶性温。使用时需捣碎。治疗男子阴部肿胀，将鲜叶捣烂，混合醋封贴患处。女性患者可用绵布包裹塞入阴道内，三到四次更换一次。萧炳说：又有大荏，形状类似野荏，植株高大硕壮，叶片大小是小荏的一倍，不能食用。人们收集其种子，用来浸透绢帛，与大麻子相同。小荏的种子快要成熟时，人们采摘其豆荚食用，非常香美。大荏的叶子不能食用。日华子说：荏，能调顺气机，滋润心肺，促进肌肤生长，改善面色，消除积食，止住上逆之气引起的咳嗽，去除狐臭，敷治蛇咬伤。种子，能降气，止咳，补益中焦，填补精髓。
食疗方面：主治咳嗽气逆、降气。其叶捣碎，治疗男子阴部肿胀。谨按：种子压制成油使用，也有轻微破气的作用，多吃会引发心胸烦闷。
（另一段关于荏的描述）：性温。补益中气，通畅血脉，填补精髓。可以蒸熟后烈火晒干，应当张口咀嚼。春季取米食用，也可以用来休粮（辟谷）。生吃，能止渴润肺。梅师方：治疗毒蛇咬伤。用荏叶捣烂，混合猪脂，薄薄地敷在伤口上。
[Ren Zi (Perilla Seed)]
Pungent in flavor, warm in nature, non-toxic. Primarily treats cough with rebellious Qi, directs Qi downward, warms the Middle Jiao, and tonifies the body.
[Leaf]
Primarily regulates the Middle Jiao and eliminates foul odors. Harvested in the ninth lunar month, dried in the shade.
Tao Hongjing stated: Ren resembles Su (Perilla Fructus/Leaf), with tall and robust plants that are not very fragrant. When its seeds are ground and mixed with rice to make porridge, it is very nourishing and delicious, directing Qi downward and providing tonification.
People in the East call it "KT" (pronounced like 'Yu'), because its character resembles 'Su', except for the removal of the 'Grain' radical. Pressing its seeds yields oil; after sun-drying and boiling, it becomes the oil used today for coating silk fabrics and mixing with lacquer. It is also used in dietary regimens for grain avoidance (Bigu), known as heavy oil. The Tang Bencao annotation notes: The Bie Lu records that people often eat Ren leaves raw, so its seeds were considered inferior to those of Su.
Current examination of Chen Cangqi's Bencao states: Ren leaves, when crushed and applied externally, treat insect bites and swelling of the male genitals. In the Jiangdong region, oil is pressed from Ren seeds, while in the northern regions, hemp seeds are used. Both oils are suitable for coating items; however, if used for mixing lacquer, Ren oil is stronger. Ministers Yuxi et al., according to Meng Shen, state: Ren seeds have leaves that are warm in nature. They should be crushed when used. To treat male genital swelling, crush fresh leaves and apply with vinegar. For women, wrap in cotton and insert internally, changing every three or four times. Xiao Bing states: There is also a type called Da Ren (Large Perilla), which resembles wild Ren but is taller and has leaves twice the size of small Ren; it is inedible. People collect its seeds to impregnate silk fabrics, similar to hemp seeds. When small Ren seeds are nearly ripe, people harvest the pods to eat, which are very fragrant and delicious. The leaves of Da Ren are inedible. Ri Hua Zi states: Ren regulates Qi, moistens the Heart and Lungs, promotes skin growth, improves complexion, resolves stagnant food, stops cough due to rebellious Qi, eliminates fox odor, and treats snake bites. Seeds direct Qi downward, stop cough, tonify the Middle, and fill the essence and marrow.
Dietary Therapy: Primarily treats cough with rebellious Qi and directs Qi downward. Crushed leaves treat male genital swelling. Note: The seed oil has a slight Qi-dispersing effect; excessive consumption may cause chest stuffiness.
(Warm) Tonifies the Middle and benefits Qi, unblocks blood vessels, and fills the essence and marrow. It can be steamed until cooked, then dried under strong sun, and chewed directly. Consuming it with rice in spring can also serve for grain avoidance. Eating raw stops thirst and moistens the lungs. Master Mei's Formula: Treats viper bites. Crush Ren leaves into a paste, mix with lard, and apply thinly to the wound.
