巴戟天，味甘、温，无毒。入心、肾二经。补虚损劳伤，壮阳道，止小腹牵痛，健骨强
筋，
定心气，益精增志，能止梦遗，此臣药，男妇俱有益，不只利男人也。世人谓其能使痿阳重
起，故云只利男子。不知阳事之痿者，由于命门火衷，妇人命门与男子相同，安在不可同补
乎。（〔批〕巴戟天男女受益，论是。）夫命门火衰，则脾胃寒虚，即不能大进饮食。用附子
、肉桂，以温命门，未免过于太热，何如用巴戟天之甘温，补其火，而又不烁其水之为妙耶
。
或问巴戟天近人罕用，止用之于丸散之中，不识亦可用于汤剂中耶？曰∶巴戟天，正汤
剂之
妙药，无如近人不识也。巴戟天，温而不热，健脾开胃，既益元阳，复填阴水，真接续之利
器，有近效，而又有远功。夫巴戟天虽入心、肾，而不入脾、胃，然入心，则必生脾胃之气
，故脾胃受其益。汤剂用之，其效易速，必开胃气，多能加餐，及至多餐，而脾乃善消。又
因肾气之补，薰蒸脾胃之气也，谁谓巴戟天不宜入于汤剂哉。
巴戟天温补命门，又大补肾水，实资生之妙药。单用一味为丸，更能补精种子，世人未
知也
。
或疑巴戟天入汤剂最妙，何以前人未见用之？曰∶前人多用，子未知之耳。夫巴戟天，
补水
火之不足，益心肾之有余，实补药之翘楚也。用之补气之中，可以健脾以开胃气；用之补血
之中，可以润肝以养肺阴。古人不特用之，且重用之。自黄柏、知母之论兴，遂置巴戟天于
无用之地。嗟乎！人生于火，而不生于寒，如巴戟天之药，又乌可不亟为表扬哉。
巴戟天，味道甘甜，性质温和，没有毒性。进入心、肾两经。能够补益虚损和劳伤，壮阳道，停止小腹部的牵引疼痛，强健骨骼和筋脉，安定心气，增加精气并增强意志，能够止住梦遗，这属于臣药（辅助君药治疗兼证或加强君药功效的药物），男女服用都有益处，不仅仅对男子有利。世人认为它能使痿弱的阳气重新勃起，所以说它只对男子有利。他们不知道阳痿是由于命门火衰引起的，妇人的命门与男子相同，怎么不可以同样进补呢？（批注：巴戟天让男女都受益，这种说法是正确的。）如果命门火衰，那么脾胃就会寒冷虚弱，就不能大量进食。使用附子、肉桂来温补命门，未免过于燥热，哪里比得上使用巴戟天的甘温之性，既能补火，又不会灼伤阴水，这才是妙处啊。
有人问：巴戟天近代人很少使用，只用在丸药和散剂中，不知道也可以用于汤剂中吗？回答说：巴戟天正是汤剂的妙药，只是近代人不了解罢了。巴戟天，性质温和而不燥热，能健脾开胃，既补益元阳，又填补阴水，真是接续阴阳的利器，既有近效，又有远功。虽然巴戟天主要入心、肾二经，而不直接入脾、胃二经，但因为它入心，就必然能生发脾胃之气，所以脾胃也受到了它的益处。在汤剂中使用它，药效容易迅速显现，一定能开胃气，让人多吃饭，等到吃得多了，脾胃才能善于消化。又因为肾气的补益，薰蒸了脾胃之气，谁说巴戟天不适合入于汤剂呢？
巴戟天温补命门，又大补肾水，确实是资助生命生成的妙药。单用这一味药制成丸剂，更能补精种子，世人并不知道这一点。
有人怀疑巴戟天入汤剂最妙，为什么前人没有见到使用它？回答说：前人大多使用过，是你不知道罢了。巴戟天，能补充水火之不足，益补心肾之有余，确实是补药中的佼佼者。用在补气药中，可以健脾以开胃气；用在补血药中，可以润肝以养肺阴。古人不仅使用它，而且重用它。自从黄柏、知母清热降火的理论兴起后，就把巴戟天放在了无用的地位。唉！人生于火，而不生于寒，像巴戟天这样的药物，怎么能不急于表彰宣扬呢？
Morinda officinalis (Bajitian), with a sweet taste and warm nature, is non-toxic. It enters the Heart and Kidney meridians. It tonifies deficiency and damage from overwork, strengthens the Yang pathway, stops pulling pain in the lower abdomen, strengthens bones and sinews, stabilizes Heart Qi, benefits essence and enhances willpower, and can stop nocturnal emission. As a Minister herb (herbs that assist the Sovereign herb in treating main symptoms or enhance its efficacy), it benefits both men and women, not just men. The world believes it causes flaccid Yang to rise again, hence saying it only benefits men. They do not know that flaccidity of sexual function is due to the decline of Fire at the Gate of Life (Mingmen). Since the Gate of Life in women is the same as in men, how can it not be supplemented similarly? (Commentary: The argument that Bajitian benefits both men and women is correct.) When Fire at the Gate of Life declines, the Spleen and Stomach become cold and deficient, making it impossible to consume large amounts of food. Using Aconite Root (Fuzi) and Cinnamon Bark (Rougui) to warm the Gate of Life is perhaps too hot; what could be more wonderful than using the sweet-warm nature of Morinda officinalis to supplement Fire without scorching Water?
Someone asked: Modern people rarely use Morinda officinalis, employing it only in pills and powders. Is it unknown whether it can be used in decoctions? I replied: Morinda officinalis is indeed a wonderful medicine for decoctions, but modern people simply do not understand it. Morinda officinalis is warm but not hot; it strengthens the Spleen and opens the stomach appetite. It both benefits Primordial Yang and fills Yin Water. It is truly an excellent tool for connecting [Yin and Yang], offering both immediate effects and long-term benefits. Although Morinda officinalis enters the Heart and Kidney, and does not directly enter the Spleen and Stomach, by entering the Heart, it necessarily generates Qi of the Spleen and Stomach; thus, the Spleen and Stomach benefit from it. When used in decoctions, its effect is rapid. It surely opens the stomach appetite, allowing one to eat more. Once eating increases, the Spleen becomes good at digestion. Furthermore, due to the supplementation of Kidney Qi steaming and warming the Qi of the Spleen and Stomach, who says Morinda officinalis is unsuitable for decoctions?
Morinda officinalis warms and tonifies the Gate of Life and greatly supplements Kidney Water. It is truly a miraculous medicine for nourishing life. Used alone as a single herb made into pills, it can further supplement essence and seed. The world does not know this.
Some doubt: If Morinda officinalis is most wonderful in decoctions, why did predecessors not see its use? I replied: Predecessors used it often; you are just unaware. Morinda officinalis supplements the insufficiency of Water and Fire and benefits the excess of the Heart and Kidney. It is truly the outstanding among tonifying herbs. When used among Qi-tonifying herbs, it can strengthen the Spleen to open the stomach appetite; when used among Blood-tonifying herbs, it can moisten the Liver to nourish Lung Yin. Ancients not only used it but also heavily relied on it. Since the theories of Phellodendron Bark (Huangbai) and Anemarrhena Rhizome (Zhimu) promoting heat-clearing and fire-descending rose, Morinda officinalis was placed in a position of uselessness. Alas! Humans are born from Fire, not from Cold. How can medicines like Morinda officinalis not be urgently praised and promoted?
