【释名】灰碱、花碱。
李时珍说：它的形状像石类中的碱，所以也得名“碱”。
【集解】李时珍说：石碱，出产于山东济宁等地。当地百姓采集蒿草、蓼草等植物，挖开地窖浸泡在水中，捞出后晒干烧成灰，用原来的水淋滤取汁液，每百斤汁液加入二、三斤面粉，时间久了就会凝结沉淀如石头一般，连同汁液一起运往各地销售，用来洗衣和发面，能获得很大的利润。其他地方用灶膛灰淋取浓汁，也能去污和发面。
【气味】味辛、苦，性温，有微毒。
【主治】去除湿热，止心痛，消痰，磨除积块，消除食滞，洗涤污垢油腻，需根据患者虚实情况使用，过量服用会损伤人体（朱震亨）。杀灭牙齿寄生虫，去除眼翳，治疗噎膈反胃，与锻石配合能腐蚀肌肉，溃破痈疽瘰疬，去除瘀血，点涂痣、疣赘、痔核，效果神奇（李时珍）。
【附方】新收录五首。

消积破气：石碱三钱，山楂三两，阿魏五钱，半夏（用皂荚水炮制过）一两，研为细末，用阿魏化开的醋煮糊制成丸药服用。（《摘玄方》）
一切眼疾：挑选石碱中无黑碎杂质的，用七层浓纸包裹悬挂在通风处，四十九天后取出，研磨至极细，每天点涂。（《普济方》）
拳毛倒睫：用刀轻轻划动患处，将药泥敷在眼睑上，睫毛自然竖起。石碱一钱，锻石一钱。用醋调匀涂抹。（《摘玄方》）

[Names] Huijian (Ash Alkali), Huajian (Flower Alkali).
Li Shizhen stated: Its appearance resembles stone alkali, hence it is also named "Jian" (Alkali).
[Collection and Explanation] Li Shizhen stated: Shi Jian (Stone Alkali) is produced in places such as Jining, Shandong. The local people harvest plants like Artemisia (Mugwort) and Polygonum (Smartweed), dig pits to soak them in water, remove them, dry them in the sun, and burn them into ash. They then leach the ash with the original water to extract the juice. For every hundred jin of juice, two or three jin of flour are added. Over time, it solidifies and precipitates like stone. It is sold along with the juice to various regions for washing clothes and leavening dough, yielding considerable profit. In other places, thick lye from kitchen stove ash is used, which also removes grease and aids in leavening.
[Properties and Flavor] Acrid, Bitter, Warm, slightly toxic.
[Indications] Eliminates damp-heat, stops heart pain, resolves phlegm, grinds down accumulations, removes food stagnation, washes away dirt and grease. Use should be measured according to the patient's deficiency or excess; excessive consumption damages the body (Zhu Zhenheng).

When combined with Duan Shi (Calcined Gypsum/Lime), it can corrode flesh, ulcerate carbuncles, sores, and scrofula, remove blood stasis, and cauterize moles, warts, hemorrhoidal nodes with divine efficacy (Li Shizhen).
