气味甘寒，无毒。主治伤中，五劳六极，羸瘦崩中，绝脉，补虚，益气。（《纲
目》误书中品，夫桑上之寄生得列上品，岂桑反在中品也，今改入上品。）
（桑处处有之，而江浙独盛。二月发叶，深秋黄陨，四月椹熟，其色赤黑，味甘性温。）
桑名白桑，落叶后望之，枝干皆白，根皮作纸，洁白而绵，蚕食桑精，叶丝如银，盖得阳明
金精之气。阳明属金而兼土，故味甘。阳明主燥而金气微寒，故气寒，主治伤中，续经脉也
。五劳，志劳，思劳、烦劳、忧劳、恚劳也。六极，气极、血极、筋极、骨极、肌极、精极
也。羸瘦者，肌肉消减。崩中者，血液下注。脉绝者，脉络不通。桑皮禀阳明土金之气，刈
而复茂，生长之气最盛，故补续之功如此。
气味苦寒，主除寒热，出汗。
（按∶《夷坚志》云∶严州山寺有一游僧，形体羸瘦，饮食甚少，每夜就枕，遍身汗出，
迨
旦衣皆湿透，如此二十年无药能疗，期待尽耳。监寺僧曰∶吾有药绝验，为汝治之，三日宿
疾顿愈，其方单用桑叶一味，乘露采摘，焙干碾末，每用二钱，空腹温米饮调服。或值桑落
时，干者亦堪用，但力不如新采者，桑叶是止盗汗之药，非发汗药。《本经》盖谓桑叶主治
能除寒热，并除出汗也，恐人误读作发汗解故表而明之。）
【桑根白皮】
气味甘寒，无毒。主治损伤中气，五种劳损和六种极度虚弱，身体消瘦及崩漏，脉绝（脉搏微弱或消失），补益虚损，益气。（《本草纲目》错误地将其列为中品，既然寄生在桑树上的桑寄生被列为上品，难道桑树反而在中品吗？现在改正列入上品。）
（桑树各地都有，但江浙地区特别茂盛。二月长叶，深秋变黄落叶，四月桑葚成熟，颜色赤黑，味道甘甜，性质温和。）
桑树名为白桑，落叶后远望，枝干皆白，根皮可造纸，洁白且绵软，蚕吃桑叶精华，吐出的丝像银子一样，这是因为得到了阳明金精之气。阳明经属金而兼有土性，所以味道甘。阳明主燥而金气微寒，所以性质寒。主治损伤中气，接续经脉。五劳，指志劳、思劳、烦劳、忧劳、恚劳（愤怒导致的劳损）。六极，指气极、血极、筋极、骨极、肌极、精极。羸瘦，指肌肉消减。崩中，指血液下注（大量出血）。脉绝，指脉络不通。桑皮禀受阳明土金之气，割刈后又能重新茂盛，生长之气最盛，所以具有如此补续的功效。
【桑叶】
气味苦寒，主治去除寒热，出汗。
（按：《夷坚志》记载：严州山寺有一位游方僧人，形体消瘦，饮食很少，每晚躺下睡觉时，全身出汗，等到天亮衣服都湿透了，这样持续了二十年，没有药能治愈，只能等待死亡罢了。监寺僧人说：我有非常灵验的药，为你治疗，三天后宿疾立刻痊愈，其方单用桑叶一味，趁露水采摘，焙干碾成粉末，每次用二钱，空腹用温米汤调服。或者遇到桑叶落下时，干桑叶也可以使用，但药效不如新采的。桑叶是止盗汗（夜间睡眠中出汗）的药，不是发汗药。《神农本草经》大概是指桑叶主治能除寒热，并消除出汗症状，恐怕人们误读为发汗解表，所以加以说明。）
[Sangbaipí (Cortex Mori)]
Taste: Sweet, Cold. Toxicity: Non-toxic. Indications: Treats injury to the Middle Jiao (Middle Burner), five types of chronic fatigue (Wulao) and six extremes of debility (Liují), emaciation, metrorrhagia (Bengzhong), pulse disappearance (Juemai), tonifies deficiency, and benefits Qi. ([Bencao Gangmu] erroneously listed it in the Middle Grade; since Sangjisheng (Mulberry Mistletoe) growing on mulberry trees is listed in the Upper Grade, how can the Mulberry tree itself be in the Middle Grade? It is now corrected and placed in the Upper Grade.)
(Mulberry trees are found everywhere, but are particularly abundant in Jiangsu and Zhejiang provinces. Leaves emerge in February, turn yellow and fall in late autumn, and mulberries ripen in April, appearing dark red-black, with a sweet taste and warm nature.)
The mulberry is named "White Mulberry" because after leaf fall, the branches and trunks appear white from afar. The root bark is used for paper, being white and fibrous. Silkworms consume the essence of mulberry leaves and spin silk like silver, indicating that it obtains the Qi of Yangming Metal Essence. The Yangming channel belongs to Metal and incorporates Earth, hence its sweet taste. Yangming governs Dryness, and Metal Qi is slightly cold, hence its cold nature. It treats injury to the Middle Jiao and reconnects meridians. "Five Fatigues" refer to mental fatigue (Zhilao), overthinking (Silao), vexatious fatigue (Fanlao), worry-induced fatigue (Youlao), and anger-induced fatigue (Huilao). "Six Extremes" refer to extremes of Qi, Blood, Tendons, Bones, Flesh, and Essence. Emaciation refers to muscle wasting. Metrorrhagia refers to downward flow of blood (profuse bleeding). Pulse disappearance refers to blocked meridians. Sangpi inherits the Qi of Yangming Earth and Metal; it grows lush again after harvesting, possessing vigorous growth Qi, thus having such powerful tonifying and reconnecting effects.
[Sangye (Folium Mori)]
Taste: Bitter, Cold. Indications: Eliminates chills and fever, stops sweating.
(Note: [Yijian Zhi] records: A wandering monk in a mountain temple in Yanzhou was emaciated and ate very little. Every night when he lay down to sleep, his whole body would sweat until dawn, soaking his clothes completely. This persisted for twenty years without any medicine able to cure him; he could only await death. The temple supervisor said: I have a highly effective medicine to treat you. After three days, the chronic illness was instantly cured. The prescription consisted solely of Sangye (Mulberry Leaf). Harvested while covered with dew, dried by roasting, and ground into powder, two qian were taken each time, mixed with warm rice water on an empty stomach. If harvested during the time when leaves fall, dried leaves can also be used, though their efficacy is not as strong as freshly picked ones. Sangye is a herb that stops nocturnal sweating (Daohan), not a diaphoretic herb. The [Shennong Bencao Jing] likely meant that Sangye treats chills and fever and eliminates sweating symptoms. To prevent misunderstanding it as a herb for inducing sweating to release the exterior, this clarification is provided.)
