Detailed Explanation of the Cultivation Techniques and Processing Methods of Dog Gallstone

Dog gallstone (gou bao) refers to the gastric stones, bladder stones and gallstones etc. removed from the body of a dog. The main components of dog gallstone are: calcium carbonate, magnesium carbonate, magnesium sulfate, etc. It has the functions of descending adverse qi, relieving stagnation and detoxifying. It is mainly used to treat distension and fullness of the chest and hypochondrium, esophageal cancer, stomach cancer, nausea and vomiting, boils and sores, etc. It is an important raw material for many fine medicines, and together with cow bezoar and cinnabar it is ranked among the "Three Treasures."

1. There are two cultivation methods: the feeding cultivation method and the surgical method. General farmers commonly use the feeding cultivation method. The surgical method must be performed by professional technical personnel. The feeding cultivation method is described below: take a pinch of horsetail hair or human hair, roll it into a ball, wrap it with a piece of meat or a steamed bun and feed it to the dog, once in the morning and once in the evening, for 3 consecutive days. Be careful to check whether it is excreted in the feces; if it is excreted, it must be fed again, until these foreign objects are no longer excreted within one week. Alternatively, thoroughly mix 200 grams each of human hair, pig hair and wool, 150 grams of decomposing alcohol (primary isoamyl alcohol) and 300 grams of water, place in a pot and heat to dissolve, then pour out and feed to the dog, twice a day in the morning and evening, 50 grams each time, for about half a month.

2. Feeding management during the period of cultivating dog gallstone. The feed nutrition must be comprehensive, mainly meat, and in particular more cholesterol-containing animal liver, lungs or other internal organs should be fed. At the same time, feed more wheat flour, bone meal and other foods containing phosphate and calcium. Feed small amounts at each meal but more meals, to avoid causing indigestion and other symptoms. The dog kennel should be quiet, with a dry and clean floor. Keep the dog penned separately and strengthen care; let it walk freely for half an hour every day, and do not let it become overly fatigued. At this time the dog's resistance is relatively poor, and once illness occurs it must be treated promptly.

3. There are two methods for removing dog gallstone. One is to let the dog die naturally or kill the dog to obtain the stone. The other is to anesthetize the dog and remove the stone surgically. Whichever method is used, the gallbladder, liver, stomach, hepatic duct, bile duct, etc. must all be carefully examined. Good-quality dog gallstone sells for more than one hundred yuan per gram, and the profit is extremely considerable.

4. During processing, remove the coarse outer membrane completely, wash clean and dry in the shade; it must never be exposed to wind or sunlight. Dog gallstone is round or oval in shape, generally 1.8-3 cm in diameter, with a grayish-white or grayish-black surface, natural lines, slightly smooth, solid and fine in texture, showing marks when scratched with a fingernail, with concentric ring layers on the cross-section, and a powdery feeling when chewed. Generally a single dog gallstone, after removing the core, weighs about 2-7 grams.
