Nature and flavor: Cold, non-toxic. It moistens the five Zang organs (Five Viscera), treats Xiao Ke (wasting-thirst syndrome), opens the stomach (appetite), resolves alcohol toxicity, and is indicated for Lao Pi (chronic accumulation masses) and conditions characterized by alternating cold and heat, as well as blood masses in women; it can be consumed after boiling. Although its nature is cold, it is contrary to Dan Shi (cinnabar and other mineral drugs); those who consume Dan Shi should avoid eating it, as it causes abdominal knotting and pain. [Newly observed by Chen Cangqi, Ri Huazi.]
The *Tu Jing Ben Cao* details are recorded under the entry for "Ma Dao" (Machiaria).
Chu Yushi considers it miraculous for treating scalds and burns. Burn clam shells to ash, grind into powder, mix with oil, and apply topically. The *Ji Yan Fang* records the same method.
Nature: Cold, non-toxic. Treats Shi Qi (epidemic febrile diseases), opens the stomach, suppresses the effects of Dan Shi drugs and Ding Chuang (carbuncles), drains dampness, promotes lactation, and is beneficial when boiled with fermented grain residue (Zao). Soak fresh clams to extract juice and wash Ding Chuang. Excessive consumption induces coughing and cold qi, damaging the Kidneys. Old shells treat Yin Chuang (genital ulcers) and stop dysentery. Xi Rou (Clam meat): Cold in nature, removes sudden heat, brightens the eyes, promotes urination, descends hot qi, treats Hong Kong Jiao (podagra/foot swelling), damp-toxicity, resolves alcohol toxicity, and treats yellow eyes. Drink the extracted juice to treat Xiao Ke. Rotten shells: Warm in nature, burn to white ash and take with water to treat Fan Wei (regurgitation/vomiting) and remove phlegm-fluid retention in the chest and heart. Shells stored for a long time treat Wei Fan (gastric regurgitation) and loss of essence. [Newly observed from *Tang Ben Zhu*, Chen Cangqi, Ri Huazi.]
The *Tu Jing Ben Cao* details are recorded under the entry for "Ma Dao".
Chen Cangqi states: Xi (Clam) is smaller than Ge (Clam), black in color, lives in muddy water, and can fly using its shell as wings during wind and rain. The *Sheng Hui Fang* treats sudden persistent coughing. Use white clam shells in any quantity, crush and grind to an extremely fine powder. Take one Qian Bi (approx. 3-5g) mixed with rice drink, three to four times daily; it is excellent.
Burn clam shells to powder and ingest them to treat hemorrhoids. [Newly observed by Chen Cangqi]
The *Tu Jing Ben Cao* details are recorded under the entry for "Ma Dao".
Chen Cangqi says: Jin (a type of clam), also called Sheng Jin. It has hair-like structures similar to clams, is long and flat. Burning the shell to powder and ingesting it treats Ye Ji Bing (wild chicken disease, a chronic wasting condition). Eating its flesh has no medicinal utility.
Beng (Freshwater Mussel)
Nature: Cold, non-toxic. Brightens the eyes, stops Xiao Ke, eliminates vexation, resolves heat toxicity, tonifies deficiency and exhaustion in women, treats lower bleeding, hemorrhoids, metrorrhagia, and leukorrhea, and suppresses Dan Shi drug toxicity. Insert Huang Lian Mo (Coptis powder) into the mussel, extract the juice, and apply to red eyes and dim vision; it is effective. Powdered rotten mussel shell taken with water treats Fan Wei and Tan Yin (phlegm-fluid). This refers to the large mussels described by Bao Zhuang. Furthermore: Beng Fen (Mussel powder) is cold and non-toxic. Treats Gan Ji (infantile malnutrition), stops dysentery and vomiting/regurgitation. For abscesses and swellings, mix with vinegar and apply externally; it also counteracts Ting Li Shi (Realgar). [Newly observed by Ri Huazi]
The *Tu Jing Ben Cao* details are recorded under the entry for "Ma Dao".
Chen Cangqi cites Tao Hongjing: Large Ge (Clam) is actually Beng (Mussel). According to analysis, Beng is cold in nature; boiling it treats female deficiency exhaustion, lower bleeding, brightens eyes, drains dampness, and stops Xiao Ke. Old mussels contain pearls; their shells can be made into powder. Rotten mussel shell powder taken with water treats Fan Wei and phlegm-fluid retention in the chest and heart. They grow in rivers, streams, and ditches. Tao Hongjing’s claim that they are large clams is erroneous. The *Shi Liao Ben Cao* states that Beng is greatly cold. It treats severe heat, resolves alcohol toxicity, stops thirst, and removes eye redness. It agitates cold and hot qi. The *Dan Fang Jing Yuan* records using Beng Fen to refine Liu Huang (Sulfur).
