Eel (Shanyu), with a sweet taste and strongly warm nature, is non-toxic. It enters the Spleen and Kidney meridians. It tonifies the middle and boosts Qi, further stimulates Yang, disperses dampness, removes fox odor, and generates body fluids to quench thirst and restore strength. Smearing eel blood on facial paralysis can treat deviation of the mouth and eyes, serving as an emergency treatment. Additionally, it treats erysipelas (Huodan) characterized by redness and swelling; applying eel blood topically is effective.
One asks: Does using eel together with [missing character, likely referring to itself or a specific part] enhance Qi and strength? The answer is: Yes. However, only those eels with a crest on their heads are effective when used.
Crab (Xie), with a salty taste and cold nature, is toxic. It dissipates blood stasis, resolves accumulation, tonifies Qi, and nourishes tendons. It eliminates heat and oppression in the chest, reduces facial swelling and facial paralysis, and heals lacquer poisoning (Qichuang). It reconnects tendons and bones. If consumed by individuals with chronic diseases, these conditions may recur. If pregnant women consume it, it may cause difficult labor (transverse presentation). This substance is most detrimental to humans, yet people love to eat it most. However, using it to dissipate chest heat has some merit. If used in medicine, it is employed solely for treating traumatic injuries.
One asks: Do crab claws primarily break the amniotic sac to induce abortion because their claws are excessively sharp? The answer is: Crab nature is highly active, and its claws are the most active of all. When a fetus dies in the womb and the placenta cannot be expelled, using crab claws is truly miraculous, precisely taking advantage of their active, moving nature. (Commentary: Human placentas are delivered directly, whereas crab claws move sideways; thus, they are used to break the placenta. This must not be overlooked.)
Seahorse (Haima), also belonging to the shrimp family. It enters the Kidney meridian and Mingmen Gate. It specializes in stimulating Yang, with efficacy not inferior to that of sea dog (Felinus maritimus), though this is unknown to many. It is also adept at inducing abortion, thus capable of promoting labor. Its functions are comparable to Tan'na Qi (sea dog penis), yet people value Tan'na Qi over seahorse, which is a confusion of the world. Who knows that seahorses, regardless of gender, [text missing here in source]...
One asks: Which region produces the best seahorses? Seahorses are abundant along the coast, but those from Shandong are best for stimulating Yang, followed by Guangdong. This is likely because Shandong seahorses possess more vital energy (Shengqi). Abundant Yang energy particularly aids conception.
Clam (Wenge), with bitter and salty tastes and neutral-cold nature, is non-toxic. It promotes urination, resolves phlegm, drives away hypochondriac stiffness and lower back pain, relieves throat cough and chest bi syndrome, astringes metrorrhagia and leukorrhea, and reduces flat tumors, scrofula, and hemorrhoids. Master Zhang Zhongjing used it in formulas for Cold Damage (Shanghan), valuing its ability to promote urination, direct action to the Kidneys, resolve phlegm, and soften hardness.
