【气味】
味甘、性寒，无毒。归入足太阳膀胱经。
【主治】
通利小便。清除胃中积聚的寒热邪气。疏通九窍及六腑的津液运行。消除体内停滞的结聚，缓解口渴。因为滑石具有甘淡的味道，首先进入胃部，渗透并走向经络，流动增益津液与气机，向上输送至肺脏，向下通达膀胱。肺主司皮毛，是水的上源；膀胱负责管理津液，通过气化作用使津液排出。滑石在上能发散表邪，在下能通利水道，是清除热邪和燥湿的药剂。发散表邪即是清除上部和中部的热邪，通利水道即是清除中部和下部的热邪。发散表邪即是燥化上部和中部的湿气，通利水道即是燥化中部和下部的湿气。热邪消散则三焦安宁，表里调和；湿气去除则阑门（肠道下口）通畅，阴阳平衡。刘河间使用益元散，通治表里上下各种疾病，大概是深刻明白了这一原理。
【气味】
味辛、性温，无毒。药性轻浮上升，属于阳。归入手太阴肺经和足厥阴肝经。
【主治】
疏通关节。解除疲劳乏力。治疗小儿风痰。促使毒邪随汗发出。清利头目的风热。能够引导其他药物进入营分和卫分。又治疗骨蒸劳热。疏理肝气。又主治肺气盛实。
【气味】
味甘、性温，无毒。药性轻浮上升，属于阳。归入手太阳小肠经和足太阳膀胱经。又通行足阳明胃经和足太阴脾经。是作用于肝经气分的药物。
【主治】
治疗风病通用。泻除肺实效果如神。疏散头部和眼目中的滞气。祛除上焦的风邪。虽然它的地位如同士兵般卑微低贱，但跟随引经药的作用无处不到。如果要补益脾胃，没有这种引导药就不能发挥作用。凡是脊背疼痛、项部僵硬不能回顾，腰部像要折断，项部像被拉扯的情况，这是手足太阳经的病证，不用此药不能发散。凡是疮疡在胸膈以上，即使没有手足太阳经的病证，但风邪结聚于上部，不用此药不能宣散。在泻黄散中加倍使用防风，是为了在土中泻木（即健脾抑肝）。得到葱白配合能通行周身。得到泽泻和白芷配合治疗风病。得到当归和芍药配合治疗妇女子宫风邪。

[Flavor and Nature]
Sweet, cold, non-toxic. Enters the Foot-Taiyang (Bladder) Meridian.
[Maintaining Health / Indications]
Promotes urination. Clears accumulated cold and heat in the stomach. Unblocks the fluid metabolism of the Nine Orifices and Six Fu Organs. Removes stagnation and stops thirst. Since Talcum (Huashi) has a sweet and bland flavor, it first enters the Stomach, permeates and moves through the meridians, circulating to benefit fluids and Qi, transporting upwards to the Lung, and downwards to the Bladder. The Lung governs the skin and hair and is the upper source of water; the Bladder manages fluids, and through Qi transformation, they are excreted. Talcum can release the exterior from above and promote water pathways from below; it is an agent that clears heat and dries dampness. Releasing the exterior clears heat from the Upper and Middle Jiao; promoting water pathways clears heat from the Middle and Lower Jiao. Releasing the exterior dries dampness in the Upper and Middle Jiao; promoting water pathways dries dampness in the Middle and Lower Jiao. When heat dissipates, the Triple Burner becomes tranquil, and the interior and exterior harmonize. When dampness is removed, the Lanmen (lower opening of the intestines) becomes unobstructed, and Yin and Yang flow smoothly. Liu Hejian used Yi Yuan San (Benefit Prime Powder) to treat various diseases of the interior, exterior, upper, and lower parts, presumably because he deeply understood this principle.
[Flavor and Nature]
Pungent, warm, non-toxic. Light and ascending, belonging to Yang. Enters the Hand-Taiyin (Lung) and Foot-Jueyin (Liver) Meridians.
[Maintaining Health / Indications]
Unblocks joints. Relieves fatigue and debility. Treats pediatric wind-phlegm. Induces sweating to expel toxins. Clears wind-heat from the head and eyes. Can guide other herbs into the Ying (Nutritive) and Wei (Defensive) levels. Also treats bone-steaming consumptive fever. Explores and regulates Liver Qi. Also treats excess conditions of the Lung.
[Flavor and Nature]
Sweet, warm, non-toxic. Light and ascending, belonging to Yang. Enters the Hand-Taiyang (Small Intestine) and Foot-Taiyang (Bladder) Meridians. Also circulates through the Foot-Yangming (Stomach) and Foot-Taiyin (Spleen) Meridians. It is a herb acting on the Qi level of the Liver Meridian.
[Maintaining Health / Indications]
Generally treats wind disorders. Effectively drains Lung excess. Disperses stagnant Qi in the head and eyes. Eliminates wind pathogens in the Upper Jiao. Although its status is humble like that of common soldiers, it reaches everywhere following its guiding function. If tonifying the Spleen and Stomach, without this guiding agent, the treatment cannot proceed. For cases of spinal pain, neck stiffness with inability to look back, waist feeling as if broken, and neck feeling as if pulled, these are symptoms of the Hand and Foot Taiyang meridians; without this herb, dispersion is not possible. For sores located above the chest and diaphragm, even without Hand and Foot Taiyang symptoms, if wind is knotted in the upper part, without this herb, dissemination is not possible. In Xie Huang San (Drain Yellow Powder), Fangfeng (Saposhnikovia Root) is doubled to drain Wood within Earth (i.e., suppress Liver overacting on Spleen). Combined with Scallion White (Congbai), it circulates throughout the body. Combined with Alisma (Zexie) and Angelica Dahurica (Baizhu/Bai Zhi context implies Bai Zhi here for wind), it treats wind. Combined with Dang Gui (Angelica Sinensis) and Shao Yao (Peony), it treats uterine wind in women.
Incompatible with: Veratrum (Lilu), Ginger (Ganjiang).
Detoxified by: Dioscorea Hypoglauca (Bixie) neutralizes the toxicity of Aconite (Fuzi).
