气味甘平，无毒。主补中、益气。久服肥健，不老神仙。
（大麻即火麻，俗名黄麻。始出泰山川谷，今处处种之，其利颇饶。叶狭茎长，五六月
开细
黄花成穗，随结子可取油。《齐民要术》曰∶麻有雌雄，于放花时拔出雄者，若未花先拔，
则不结子。）
大麻放花结实于五六月之交，乃阳明太阴主气之时。《经》云∶阳明者，午也。五月盛
阳之
阴也。又，长夏属太阴主气，夫太阴、阳明，雌雄相合，麻仁禀太阴、阳明之气，故气味甘
平。主补中者，补中土也。益气者，益脾胃之气也。夫脾胃气和则两土相为资益，阳明燥土
得太阴湿气以相资，太阴湿土得阳明燥气以相益，故久服肥健，不老神仙。
气味甘平，无毒。主治伤中虚羸，补五内，益气力，长肌肉，填髓脑。久服轻身不
老。
（巨胜一名胡麻，一名狗虱。本出胡地，故名胡麻。巨，大也。本生胡地大宛，故又名
巨胜
，八谷之中，唯此为良。寇宗 曰∶胡麻正是今之大脂麻，独胡地所产者肥大，因名胡麻
，
又名巨胜。今市肆中一种形如小茴，有壳无仁，其味极苦，伪充巨胜。夫巨胜即胡麻，是属

麻乃五谷之首，禀厥阴春生之气。夫五运始于木，而递相资生。主治伤中虚羸者，气味
甘平
，补中土也。补五内，益气力，所以治伤中也。长肌肉，填髓脑，所以治虚羸也。补五内，
益气力之无形，长肌肉，填髓脑之有形，则内外充足，故久服轻身不老。
气味甘平，无毒。主要功效为补益中焦、益气力。长期服用可使身体丰满健壮，达到不老如神仙的境界。
（大麻即火麻，俗称黄麻。最初产于泰山山谷，如今各地都有种植，其利益颇为丰厚。叶片狭长茎干细长，五六月间开出细小的黄花结成穗状，随即结出种子可榨油。《齐民要术》记载：麻有雌雄之分，在开花时拔出雄株，如果未开花就先拔除，则不结种子。）
大麻在五六月份之交开花结实，此时正值阳明经和太阴经主气之时。《内经》说：阳明对应午时。五月是盛阳之中蕴含阴气的时候。另外，长夏属于太阴主气，太阴与阳明，如同雌雄相合，麻仁禀受了太阴和阳明二经之气，所以气味甘平。所谓“主补中”，是指补益中土（脾胃）。所谓“益气”，是指补益脾胃之气。脾胃之气调和，则脾（阴土）与胃（阳土）相互资助增益，阳明燥土得到太阴湿气的滋润而相互资益，太阴湿土得到阳明燥气的温煦而相互补益，因此长期服用能使身体丰满健壮，青春不老。
气味甘平，无毒。主治损伤中焦导致的虚弱消瘦，补益五脏，增强气力，生长肌肉，填补髓脑。长期服用可使身体轻盈，延缓衰老。
（巨胜又名胡麻，又名狗虱。原本产于胡地，所以叫胡麻。“巨”意为大。原本生于胡地的大宛国，所以又名巨胜。在八谷之中，只有它最为优良。寇宗奭说：胡麻正是现在的大脂麻，只有胡地产的肥大，因此名为胡麻，又名巨胜。现在市场上有一种形状像小茴香，有壳无仁，味道极苦，假冒充作巨胜。夫巨胜就是胡麻，属于谷物类，刘晨阮肇深入天台山，仙女用胡麻饭招待他们，如果有壳无仁且味道苦涩，怎么能够做饭吃呢？必须知道市场上所谓的巨胜其实是野生的狗虱，所以有壁虱胡麻的名字。壁虱、狗虱不堪入药。如果没有胡麻，应当从脂麻中挑选颜色赤红且肥大的使用，这样才不至于出错。）
麻是五谷之首，禀受厥阴肝木春生之气。五运始于木，并依次相生。主治损伤中焦导致的虚弱消瘦，是因为其气味甘平，能补益中土。补益五脏，增强气力，是用来治疗中焦损伤的。生长肌肉，填补髓脑，是用来治疗身体虚弱的。补益五脏和气力属于无形之补，生长肌肉和填补髓脑属于有形之补，这样内外充足，所以长期服用可使身体轻盈，延缓衰老。
[Da Ma Ren (Hemp Seed) / Ju Sheng Zi (Sesamum Indicum)]
The flavor is sweet and the nature is neutral, non-toxic. It primarily tonifies the Middle Jiao and benefits Qi. Long-term consumption leads to a plump and robust physique, conferring the state of being ageless like an immortal.
(Hemp refers to Fire Hemp, commonly known as Yellow Hemp. It originally grew in the valleys of Mount Tai, but is now cultivated everywhere, providing considerable benefit. The leaves are narrow and the stems long; in May and June, it blooms with small yellow flowers forming spikes, subsequently bearing seeds from which oil can be extracted. *Qimin Yaoshu* states: Hemp has male and female plants. The male plants should be pulled out when flowering. If removed before flowering, no seeds will form.)
Hemp flowers and bears fruit at the transition between May and June, a time when the Yangming and Taiyin meridians govern the Qi. The *Classic* states: Yangming corresponds to Wu (noon). The fifth month contains Yin within abundant Yang. Furthermore, Late Summer belongs to the Taiyin governing Qi. Taiyin and Yangming, like male and female combining, Hemp Seed inherits the Qi of both Taiyin and Yangming, hence its flavor is sweet and nature neutral. "Primarily tonifying the Middle" refers to tonifying the Central Earth (Spleen and Stomach). "Benefiting Qi" refers to benefiting the Qi of the Spleen and Stomach. When the Qi of the Spleen and Stomach harmonizes, the two Earth elements mutually support and benefit each other. The Dry Earth of Yangming receives moistening from the Damp Earth of Taiyin for mutual support, while the Damp Earth of Taiyin receives warming from the Dry Qi of Yangming for mutual benefit. Thus, long-term consumption leads to a plump and robust physique, preventing aging.
The flavor is sweet and the nature is neutral, non-toxic. It treats deficiency and emaciation caused by injury to the Middle Jiao, tonifies the Five Zang Organs, enhances strength, promotes muscle growth, and fills the marrow and brain. Long-term consumption makes the body light and prevents aging.
(Ju Sheng is another name for Hu Ma [Sesame], also known as Dog Louse. It originally came from Hu lands, hence the name Hu Ma. "Ju" means large. It originally grew in Dayuan of Hu lands, hence also named Ju Sheng. Among the Eight Grains, it is considered the finest. Kou Zongshi said: Hu Ma is precisely what is now called Da Zhi Ma [Black Sesame]. Only those produced in Hu lands are plump and large, thus named Hu Ma, also Ju Sheng. Currently, there is a type in the market shaped like cumin, with husk but no kernel, tasting extremely bitter, falsely passed off as Ju Sheng. Since Ju Sheng is Hu Ma, belonging to the grain category, when Liu Chen and Ruan Zhao entered Tiantai Mountain, fairies fed them Hu Ma rice. If it had husks without kernels and tasted bitter, how could it be made into rice? One must know that the so-called Ju Sheng in the market is actually wild Dog Lice, hence the name Wall Louse Hu Ma. Wall Lice and Dog Lice are unsuitable for medicinal use. If Hu Ma is unavailable, one should select red-colored and plump varieties from Zhi Ma [Sesame] for use, to avoid error.)
Hemp is the head of the Five Grains, inheriting the Spring-born Qi of Jueyin Liver Wood. The Five Movements begin with Wood and generate each other in sequence. Treating deficiency and emaciation caused by injury to the Middle Jiao is because its sweet and neutral flavor tonifies the Central Earth. Tonifying the Five Zang Organs and enhancing strength serves to treat injury to the Middle Jiao. Promoting muscle growth and filling the marrow and brain serves to treat emaciation. Tonifying the Five Zang Organs and Qi involves intangible nourishment, while promoting muscle growth and filling marrow/brain involves tangible nourishment. With internal and external abundance achieved, long-term consumption makes the body light and prevents aging.
