{"product_id":"ark-shells-whole-arca-granosa","title":"Ark Shells Whole (Arca Granosa)","description":"\u003cp class=\"PDq2pG_selectionAnchorContainer\"\u003eArk Shells Whole (Arca granosa) are the cleaned whole shells of the ark clam, traditionally used in Traditional Chinese Medicine (TCM) as a mineral-rich animal-derived materia medica. Known in Chinese herbal practice as Wǎ Léng Zǐ (瓦楞子), ark shell has historically been valued for its ability to support digestive comfort, soften hardness, and help regulate excess stomach acidity according to traditional use. Its nature is generally considered salty and neutral, making it a distinctive traditional ingredient used in carefully formulated preparations.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eIn traditional use, Ark Shell is typically cleaned, calcined, crushed, or powdered before being incorporated into decoctions or formulas rather than used in its raw whole-shell form. It has historically been used to support stomach comfort, ease occasional sour regurgitation, and help address accumulations or firmness according to TCM principles. Because the shell is highly mineralized, traditional processing methods are used to make it more suitable for formulation.\u003c\/p\u003e\n\u003cp\u003eArk Shell is also traditionally associated with phlegm and mass-softening applications, where it has been incorporated into formulas intended to soften hardness and support normal tissue balance. In TCM practice, it is often combined with other herbs depending on the individual's pattern rather than used as a stand-alone remedy.\u003c\/p\u003e\n\u003cp\u003eModern analysis shows that ark shells are composed primarily of calcium carbonate, along with smaller amounts of other naturally occurring minerals and trace elements. Their high mineral content helps explain their historical use in traditional preparations intended to buffer acidity and provide a mineral-based balancing effect.\u003c\/p\u003e\n\u003cp\u003eEach batch of Ark Shells Whole (Arca granosa) is carefully cleaned and selected to preserve its natural shell structure, mineral content, and traditional quality. The whole shells are suitable for traditional processing, educational use, herbal formulation, and materia medica applications where authentic ark shell is required.\u003c\/p\u003e","brand":"Khan Hing Tong","offers":[{"title":"1 oz","offer_id":71202287124733,"sku":"LA-6671","price":3.12,"currency_code":"USD","in_stock":true},{"title":"2 oz","offer_id":71202287157501,"sku":"LA-6672","price":5.0,"currency_code":"USD","in_stock":true},{"title":"1\/2 lb","offer_id":71202287190269,"sku":"LA-6673","price":14.29,"currency_code":"USD","in_stock":true},{"title":"1 lb","offer_id":71202287223037,"sku":"LA-6674","price":19.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/6732\/8765\/files\/ChatGPTImageAug29_2026_02_23_53AM.png?v=1787995464","url":"https:\/\/laherb.com\/en-ca\/products\/ark-shells-whole-arca-granosa","provider":"LA Herb","version":"1.0","type":"link"}
