《百草镜》记载：石蛤生长在山野土壤中，根皮呈红色，药用部分为根部。周维新说：石蛤就是映山红（杜鹃花）的根。《花镜》记载：山踯躅，俗称映山红。形态类似杜鹃花但稍大，花瓣单瓣且颜色淡，如果山上长满这种花，当年必定丰收。有红色和紫色两种，红色的可以取汁液用来染物。李氏《草秘》记载：石蛤苗高二三尺，茎呈方形，叶子像竹叶，根部形状像蛤蜊，质地坚硬如石头。我赵学敏按语：汪连方《方》记载：映山红的根名叫翻山虎，当地人叫它搜山虎，治疗风邪能拔除病根。医家将风合巴山虎蒸酒后服用，名叫二虎丹。考察其功效，虽然相差不大，但究其形态，确实不是同一种植物，应当以李氏《草秘》所载为准。煎水外洗梅疮（梅毒引起的皮肤溃烂），能消除风疹块。
风气痛：祝穆《效方》记载：地蜈蚣草、石蛤草，各等分，用绍兴酒煎服。
肠痈（阑尾炎等肠道化脓性炎症）：张景岳《新方》记载：肠痈生于小腹角落，轻微肿胀且小腹隐痛不止的就是。如果毒气不散，逐渐增大向内攻冲而溃破，就会造成大患。急需用此药治疗。先用红藤约一两，用好酒两碗，上午服用一次，醉卧休息；下午服用紫花地丁约一两，也像前面那样煎服，服药后疼痛逐渐停止即为有效。然后再服用散剂药物以除根。散剂方：用当归五钱、蝉蜕、僵蚕各二钱，无龙（可能指某种草药或笔误，此处保留原名）、大黄各一钱，石蛤五钱，老蜘蛛两个。在新瓦上用酒杯盖住，外部用火烘干存性，与诸药一起研为细末，空腹时用酒调服约一钱，逐日慢慢服用，病症自会消除。（《经验广集》中，石蛤使用叶片。）
秃疮：《不药良方》记载：即肥疮日久，蔓延成片，头发焦枯脱落，又名癞头疮。先用艾叶和鸽粪煎汤洗净疮痂，再用猪肉汤清洗，随即使用踯躅油，将踯躅花根四两捣烂，用菜油一碗，煎至枯焦去渣，加入少许黄蜡，用布过滤候冷，用青布蘸取涂抹，每天三次，戴上毡帽，不要见风，散发毒气，能使瘙痒停止并生发头发，久涂自然有效。
疔肿及其他各种毒疮。李氏《草秘》记载：石蛤用酒磨服，少量入口，垂死之人可救活。有此药就不必担心疔疮之患，各种肿毒，用醋磨敷患处。
Baicao Jing records: Shiha (Stone Frog, likely a local name for a plant root) grows in mountain soil; the root bark is red, and the medicinal part is the root. Zhou Weixin stated: Shiha is the root of Ying Shan Hong (Rhododendron simsii, Azalea). Huajing records: Shanzhizhu (Mountain Rhododendron), commonly known as Ying Shan Hong. It resembles the azalea but is slightly larger, with single petals that are pale in color. If it covers the mountainsides, the year will surely be abundant. There are two colors, red and purple; the red variety can have its juice extracted to dye materials. Li's Caomi records: The seedling of Shiha grows two or three chi tall, the stem is square, leaves resemble bamboo leaves, and the root shape resembles a clam, hard as stone. I, Zhao Xuemin, note: Wang Lianfang's Fang records: The root of Ying Shan Hong is named Fanshan Hu (Mountain-Climbing Tiger); locals call it Soushan Hu. It treats wind pathogens by pulling out the root cause. Physicians combine Fenghe Bashan Hu, steam it with wine, and take it orally, named Erhu Dan (Two Tigers Pill). Examining its functions, although not vastly different, investigating its morphology, they are indeed not the same species. Therefore, what is recorded in Li's Caomi should be considered correct. Decoction for washing meichuang (syphilitic sores) can eliminate wind urticaria (wind lumps).
Wind-pain: Zhu Mu's Xiaofang records: Diwugong Cao (Centipede Grass) and Shiha Cao, equal parts, decocted in Shaoxing wine and taken orally.
Changyong (Intestinal Abscess): Zhang Jingyue's Xin Fang records: Changyong occurs in the corner of the lower abdomen, characterized by slight swelling and continuous dull pain in the lower abdomen. If the toxic qi does not dissipate, it gradually enlarges, attacks inward, and ulcerates, causing major trouble. One must urgently treat it with this medicine. First, use about one liang of Hongteng (Red Vine), decocted in two bowls of good wine, taken once in the morning until drunk and sleeping; in the afternoon, take about one liang of Zihua Diding (Viola yedoensis), decocted similarly. Cessation of pain after ingestion indicates efficacy. Then, take powdered medicine to eradicate the root cause. Powder Formula: Use Danggui (Angelica sinensis) five qian, Chantui (Cicada Slough) and Jiangcan (Bombyx Batryticatus) each two qian, Wulong (possibly a typo or specific herb), Huangqi (Astragalus - *Note: Text says Da Huang Rheum, corrected contextually if needed, but strictly translating text: Da Huang*), each one qian, Shiha five qian, and two old spiders. Place on a new tile, cover with a wine cup, dry externally over fire to preserve nature (carbonize/preserve properties), grind together with other medicines into powder. Take about one qian mixed with wine on an empty stomach, taking it day by day until the condition resolves spontaneously. (Jingyan Guangji states Shiha uses leaves.)
Touchuang (Scalp Tinea/Barber's Itch): Buyao Liangfang records: This is Feichuang that has persisted for a long time, spreading into patches, with hair becoming brittle and falling out, also known as Leitou Chuang. First, wash the crusts clean with a decoction of Aiye (Mugwort Leaf) and Ge Fen (Pigeon Droppings), then wash with pork broth. Immediately apply Zhizhu You (Rhododendron Oil): crush four liang of Zhizhu flower roots, decoct in one bowl of vegetable oil until charred, remove dregs, add a small amount of Huangla (Yellow Beeswax), filter through cloth, and let cool. Apply with a blue cloth, three times daily, wear a felt hat, avoid wind, disperse toxins, stop itching, promote hair growth, and long-term application yields results.
Dingzhong (Carbuncles) and various toxic swellings. Li's Caomi records: Shiha is ground with wine and taken orally; even a small amount entering the mouth can save a dying person. With this medicine, one need not fear Dingchuang (hard carbuncles); for various toxic swellings, grind with vinegar and apply topically.
