Salty, sweet, neutral. Saw off the four edges, grind clean on a stone, process with ash-fire, coat with su (animal fat) and roast until yellow for use; some are processed with wine, vinegar, or burned to ash with pig lard. It must be ground extremely fine; otherwise, it will injure the stomach and intestines. In ancient times, both upper and lower shells were used.
Salty, neutral. Those with seven or nine ribs that have not been boiled in water are superior. For medicinal use, roast with vinegar until yellow. It is incompatible with scallions and mulberry ash, and adverse to alum and li shi (calcite).
This is what is commonly called the large turtle. Nowadays, sea turtle shells are often used to substitute it in markets, which is an error!
Salty, slightly cold. First boil in salt water for one fu period (approx. 2 hours), then roast over fire until red, grind finely, and use after the water-calcination method (shui fei). Bei Mu (Fritillaria Bulb) serves as a guiding herb; it works well with Gan Cao (Licorice), Niu Xi (Achyranthes Root), Yuan Zhi (Polygala Root), and She Chuang Zi (Cnidium Fruit). It is incompatible with Ma Huang (Ephedra), Xin Yi (Magnolia Flower), and Wu Zhu Yu (Evodia Fruit); it can subdue Sha Ren (Amomum Fruit).
Salty, sweet, cold. Select those that are complete and unperforated, wrap in silk, and boil in tofu for the time it takes to burn one incense stick. Crush and grind more than 20,000 times until fine like sifted flour for use; if not fine enough, it will damage the zang-fu organs.
Salty, cold. Boil in salt water, or wrap in dough and bake until cooked, rub off the coarse skin, grind 10,000 times, use the water-calcination method. Use those with seven pores; those with nine pores are better.
Salty, neutral. Roast over fire, grind into powder, and use after the water-calcination method; do not use in decoctions. Shu Qi (Periploca Seedling) serves as a guiding herb. It is incompatible with Gou Dan (Dog Gallbladder), Gan Sui (Kansui Root), and Yuan Hua (Genkwa Flower).
Hai Ge (Sea Clam Shell) is a general term for the broken shells of various clams in the sea, not referring specifically to one type of clam. The shells are washed by wind and waves, naturally round and clean; small ones are like fine hemp seeds, large ones...
Salty, cold. Take the shells of purple-mouthed clams, burn them to powder over charcoal fire, and use after the water-calcination method.
Method for preparing Hai Shi (Marine Limestone): Burn purple-mouthed clam shells to powder over charcoal fire. When Gua Lou (Trichosanthes Fruit) is ripe, mix the powder with the pulp and seeds, crush into a paste, form into cakes, place in bamboo segments, and hang in a ventilated place to dry in the shade. It condenses into a shell-like structure and is highly effective for resolving phlegm. Alternatively, Hai Fu Shi (Pumice) can be used instead of Hai Shi.
This refers to the feces of male sparrows. Bitter, warm, slightly toxic. Those with pointed, straight heads are male; those with rounded ends at both sides are female. Collect in the twelfth lunar month, remove attachments from both ends, grind finely, soak in Gan Cao (Licorice) water for one day, drain the water, and roast dry for use.
Bai Ding Xiang (White Sparrow Dropping): Pharmacies often adulterate this with droppings from sparrows and other birds; careful distinction is required when using.
