按∶远志入肾，非心药也，故能强志益精，与志皆肾所藏者，精虚则志衰，不能上通于心，故善忘。《灵枢》经曰∶肾藏精，精合志。肾盛怒而不止则伤志，志伤则喜忘，人之善忘者，上气不足，下气有余，肠胃实而心虚，虚则营卫留于下，久之不以时上，故善忘也。苦味中兼辛，故又能下气而走厥阴。《经》曰∶以辛补之，此水木同源之义也。
【按语】：远志进入肾经，并非单纯的心经药物，所以能强化意志、增益精髓。因为意志和精髓都是肾脏所藏的，精髓虚弱则意志衰退，不能向上通达于心，所以容易健忘。《灵枢》经文说：肾藏精，精与志相合。如果肾气大怒不止就会损伤意志，意志受损就容易遗忘。人之所以容易健忘，是因为上部正气不足，下部邪气有余，肠胃充实而心脏虚弱，虚弱导致营气和卫气滞留于下部，时间久了不能按时上行，所以容易健忘。远志的苦味中兼有辛味，所以又能降气并走向厥阴经。《内经》说：用辛味来补益（肾），这是水和木同源的深意。

（石菖蒲）正当孟夏时节禀受盛大的阳气，并结合金行的辛味而生，它的味道苦、辛，气大温，属于阳气充沛的芳香草本植物，所以无毒。
凡使勿用泥菖夏菖，如竹根鞭形黑色，气秽味腥不堪，宜采石上生者，根条嫩黄紧硬节稠，一寸有九节者佳，铜刀刮去皮节，以嫩桑条拌蒸，晒干锉用。
凡是使用石菖蒲，不要用泥菖蒲或夏菖蒲，那些像竹根鞭一样形状、颜色黑色的，气味污秽、味道腥臭不堪用。应当采集生长在石头上的，根条嫩黄、紧实坚硬、节间密集，一寸长有九个节的为佳。用铜刀刮去外皮和节部，用嫩桑枝拌和后蒸制，晒干后切碎使用。
石菖蒲，主手足湿痹，可使屈伸；贴发背痈疽，能消肿毒，下气除烦闷，杀虫愈疥疮。消目翳去头风，开心口声音，通窍益智能，耳聋耳鸣，尿遗尿数，腹痛或走者易效，胎动欲产者，能安鬼击，懵死难苏，急灌生汁∶温疟积热不解，宜浴浓汤∶单味酒煎，疗血海败，并产后下血不止∶细末铺卧，治遍身毒及不痒发痛疮疡。总阳气开发，故外充百骸，辛能四达，走窍散结，为通利心脾二经之要药也。
石菖蒲，主要治疗手足湿痹，可以使肢体恢复屈伸自如；贴敷于发背痈疽处，能消除肿胀毒素，降气解除烦闷，杀虫治愈疥疮。消除眼目翳障，去除头风，开启心窍改善言语声音，通利孔窍、增益智慧，治疗耳聋耳鸣，遗尿尿频，腹痛或游走性疼痛容易见效，胎动欲生产时，能安抚“鬼击”（一种突发性昏厥病症），对于昏迷难醒者，急需灌服新鲜汁液；温疟积热不退，适宜用浓汤洗浴；单味药酒煎，治疗血海败坏，以及产后下血不止；研成细末铺在床上，治疗全身毒症及不痒但疼痛的疮疡。总体因其阳气开发，所以向外充盈全身骨骼肢体，辛味能向四周通达，走窜孔窍、消散结滞，是通利心经和脾经的重要药物。
主治（痘疹合参） 凡痘疹惊痫神昏谵妄者可用，及痘后不着痂，溃烂成疮疥者宜入丸用，但芳草味辛多散，阴血不足心气不敛者禁之。
【主治（结合痘疹病证参考）】凡是痘疹引起的惊风癫痫、神志昏迷、胡言乱语者可以使用，以及痘疮后不结痂、溃烂形成疮疥的，适宜加入丸药中使用。但是，芳香草药味道辛散居多，阴血不足、心气不能收敛者禁用。
按∶芳香利窍，能佐地黄天冬之属，资其宣导，臻于太和，多用独用，终为气血之殃。
【按语】：芳香之品能通利孔窍，能辅助地黄、天冬这类药物，资助它们的宣通引导作用，从而达到阴阳调和的最高境界。但如果过多使用或单独长期使用，最终会成为损害气血的祸害。
Yuanzhi (Polygalae Radix) absorbs the Yang Qi of Heaven and the fragrant, potent energy of Earth in its growth; therefore, it tastes bitter and acrid, is warm in nature, and non-toxic. It is known as "Spring Yang Grass," specifically enters the Kidney Meridian, and also traverses the Heart and Spleen meridians, acting upon these three channels. For preparation, soak and wash with rice water, pound to remove the core, decoct thoroughly in concentrated Licorice Decoction (Gancao Tang), then dry in the sun for use.
Yuanzhi can dispel abnormal dreams, calm the Spirit (Shen), augment Qi, enhance intelligence, and prevent forgetfulness; it also unblocks the nine orifices, tonifies middle-jiao injuries, and expels cough with rebellious Qi, palpitations, and fright. It prevents nocturnal emission and spermatorrhea, consolidates the Heart and secures the Kidney, rendering the ears and eyes acute. It treats pediatric convulsions and epilepsy (Jing Xian), sudden fright disorders (Ke Wu), and women's aphonia due to blood stagnation (Xue Jin); its efficacy specializes in tonifying the Heart and descending to assist the Kidney. For all types of carbuncles and back sores caused by emotional depression (Seven Emotions), decoct alone and take with wine; apply the dregs externally, and they will heal. This relies on the power of bitter flavor to drain and acrid flavor to disperse.
Indications (Reference for Smallpox/Rash Diseases): After smallpox/rash, if there is Heart-evil causing unrest, it is used to calm the Spirit and stabilize memory; it is suitable for those who have been frightened.
Commentary: Yuanzhi enters the Kidney meridian and is not merely a Heart herb; thus, it strengthens will and benefits essence. Since both Will (Zhi) and Essence are stored by the Kidney, when Essence is deficient, Will declines and cannot ascend to communicate with the Heart, leading to forgetfulness. The *Ling Shu* states: "The Kidneys store Essence, and Essence harmonizes with Will." If excessive anger injures the Will, forgetfulness occurs. People prone to forgetfulness suffer from insufficient Upper Qi and excess Lower Qi; their intestines and stomach are full while the Heart is empty. Due to this emptiness, Ying (Nutritive) and Wei (Defensive) Qi remain below and fail to ascend in time, causing forgetfulness. Its bitter taste combined with acrid properties allows it to descend Qi and enter the Jueyin Meridian. The Classics state: "Use acrid to tonify [Kidney]," illustrating the principle that Water and Wood share the same source.
Shichangpu (Acori Tatarinowii Rhizoma) develops in early summer, inheriting strong Yang Qi and combining with the acrid nature of Metal. It tastes bitter and acrid, has a strongly warm nature, belongs to fragrant herbs rich in Yang Essence, and is non-toxic. When using it, do not employ Mud Acorus (Ni Chang) or Summer Acorus (Xia Chang), which resemble black bamboo root whips, have foul odors, and fishy tastes. Select those growing on rocks; the rhizomes should be tender yellow, firm, hard, and densely jointed, with nine nodes per inch being optimal. Scrape off the skin and nodes with a copper knife, steam with tender mulberry branches, dry in the sun, and chop for use.
Shichangpu primarily treats damp-bi obstruction in the hands and feet, restoring flexion and extension; applied topically to back carbuncles, it reduces swelling and toxicity; it descends Qi, relieves oppression, kills parasites, and heals scabies. It clears eye nebulae, removes Head Wind, opens the Heart orifice to improve speech, unblocks orifices, enhances intelligence, treats deafness and tinnitus, enuresis, and frequent urination; it is effective for abdominal pain or wandering pain. In cases of fetal movement threatening labor, it calms "Ghost Strike" (sudden syncope); for coma difficult to revive, urgently administer fresh juice. For warm malaria with accumulated heat unresolved, bathe in strong decoction. Decocted alone in wine, it treats Blood Sea deterioration and postpartum hemorrhage. Spread fine powder under bedding to treat systemic toxicity and painful, non-itchy ulcers. Generally, due to its opening Yang properties, it fills the body externally; its acridity spreads in all directions, traverses orifices, and dissipates nodules, making it a key herb for unblocking the Heart and Spleen meridians.
Indications (Reference for Smallpox/Rash Diseases): Suitable for smallpox/rash cases involving convulsions, epilepsy, coma, and delirium. For rashes that fail to form scabs or ulcerate into sores, it is suitable for inclusion in pills. However, since fragrant herbs are largely acrid and dispersing, it is contraindicated for those with Yin-Blood deficiency and unrestrained Heart Qi.
Commentary: Fragrant substances benefit the orifices and can assist herbs like Rehmannia Root (Dihuang) and Asparagus Tuber (Tiandong), aiding their guiding action to achieve supreme harmony. However, excessive or solitary long-term use ultimately becomes a calamity for Qi and Blood.
