[Earthworm (Baijing Di Long)]
Also known as Dilong (Earthworm). The medicinal part is the Baijing (White-necked) earthworm, which refers to the older worms.
Taste: Salty. Nature: Cold. Slight toxicity. Averse to scallions and salt. Indications: Manic delirium due to latent heat in Shanghan (Cold Damage); rambling speech due to high fever in Wenyi (Warm Diseases); epilepsy caused by febrile diseases in children; various types of stroke-like symptoms during epidemic diseases.

[Frog]
Found everywhere. Those resembling toads but with pointed mouths and slender bellies, with a bluish-green back, are Qingwa (Green Frogs). Those with yellow lines on their backs are Jinxiwan (Golden-line Frogs). Commonly known as Tuya or Shiya, also called Hazi, which is the aquatic frog (Shuiji) of today.
Taste: Sweet. Nature: Neutral-Cold. Main actions: Resolves heat toxins, promotes urination and reduces edema. Culinary use removes fatigue and weakness; particularly suitable for treating infantile malnutrition (Gan syndrome) with emaciation. For postpartum women, crushed frog juice treats Xiamawen (Mumps/Parotitis). For general whole-body edema or isolated abdominal distension, consume one or two frogs, skinned and roasted, to resolve spontaneously. For Shuigu (Hydrops/Ascites), characterized by abdominal distension, fluid sounds upon shaking, and blackish skin, use two dried frogs stir-fried with butter, seven ground beetles (Tugou) stir-fried, and half an ounce of bitter gourd (Kuhulu) stir-fried. Grind into powder. Take 2 qian with warm wine on an empty stomach. No more than three doses are needed for efficacy. During epidemics, facial redness and neck swelling are named Xiamawen. Crush Jinxiwan, mix with water, and drink in one dose on an empty stomach for extreme efficacy. For toxic dysentery causing inability to eat (Jinkou), crush one aquatic frog including intestines and viscera, heat on a tile, add 5 fen of musk, form into a cake, and apply to the umbilicus. Once qi circulation resumes, eating can resume. For various painful hemorrhoids, take one long-legged green frog, burn until carbonized (preserve nature), grind into powder, mix with snow cream, and make pills the size of wutong seeds. On an empty stomach, first eat two spoons of rice, then swallow 15 pills with Zhiqiao (Magnolia Bark) decoction. For insects eroding the anus or kidney organs, leading to anal destruction and intestinal perforation, use one frog and one part chicken bone, burn to ash, and insufflate into the lesion for great efficacy.

Ms. Miao stated that it can remove excess pathogenic heat; those with inherently weak spleen and stomach should not use it. Those with Shanghan without excess heat and mania should not use it.
