Cod-liver oil.
English Name: Cod-liver oil.
Latin Name: Gadus.
Property and flavor:
Brief introduction: Cod-liver oil is a concentrated oil from cold-water codfish, it contains the fat-soluble vitamin A and vitamin D and is relatively low in saturated fatty acids, Cod-liver oil is used as a source for essential fatty acids (EFAs) such as omega-3s like eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
Source: Common herbal classics defined the herb Cod-liver oil as the oil of the species (1).Gadus. It is a fish species of the Gadus genus, the Gadidae family (cod family). The liver oil is used medicinally. This commonly used species is introduced:
(1).Gadus.
Fish description: Gadus is long and slightly flat, its tail is prominent, and the head is larger, its mouth is slightly prominent, eyes are small, lateral upper position, the interval between eyes is wide and flat, slightly convex, big mouth, slightly lower, thick lips, there is a chin beard in the center of the lower jaw, the upper jaw is slightly longer than the lower jaw, and the rear end of the upper jaw reaches below the eye; There are several rows of fine cuspid teeth at the front end of the jaw and vomerous bone; The gill foramen is large, the operculum is interconnected and separated from the isthmus, and the head and body are covered with small round scales. It is a cold-water pelagic fish and lives in groups.
Ecological environment: Gadus is widely distributed in all oceans of the world, native to the cold waters of the North Atlantic from Northern Europe to Canada and the eastern USA (the United States of America), mainly distributed in the North Pacific and North Atlantic. Cod is an important commodity in the international market, and the main producing countries at present are Canada and Norway, USA, the United Kingdom, France, Iceland, the Faroe Islands, etc.
Growth characteristics: Gadus is a cold-water pelagic fish, which is a group fish. Most of them live in the cold sea with a water temperature of 0~16 °C (Celsius, or 32~60.8 degrees Fahrenheit). Adult fish mainly inhabit the water layer of 175~225 meters, and juvenile fish inhabit the water layer of 80~100 meters. Feed on invertebrates and small fish, such as krill, opossum shrimp, capelin, etc.
Uses of Cod: In the process of fish processing, a lot of processing wastes are produced. The content of visceral fat is high, accounting for about 20% of the total weight. Dyerber J et al. proved by experiments that fish oil is rich in unsaturated fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which have physiological functions such as lowering cholesterol, anti-inflammation, anti-allergy, preventing arteriosclerosis, preventing Alzheimer's disease, preventing cardiovascular diseases, improving brain learning function and preventing vision loss.
Cod is one of the fish with the largest annual catch in the world because of its delicious taste, few thorns, and rich nutrition. Its protein content is very high, its fat content is less than 1%, and it also contains vitamins A, D, and E. Cod is rich in DHA and DPA, which can effectively promote health benefits such as improving intelligence, eyesight and immunity, especially for pregnant women and infants. Therefore, in Northern Europe, cod is called "a nutritionist on the table".
Pharmacological actions: ①.reduce platelet aggregation; ②.relieve pain; ③.prevent a marker of advancing renal failure in NIDD(non-insulin-dependent diabetes); etc.
Studies found cod-liver oil supplements can reduce platelet aggregation and therefore lower the risks for blood clots, which can reduce possible heart attacks and strokes due to these clots. Cod-liver oil supplements can reduce musculoskeletal pain such as backache, strains, and joint pain, particularly in individuals with musculoskeletal disease. Cod-liver oil dietary supplements may help prevent a marker of advancing renal failure in non-insulin-dependent diabetes, pure eicosapentaenoic acid(EPA-E) from cod-liver oil could lower the secretion of urinary protein in NIDD(non-insulin-dependent diabetes) patient who suffers from kidney disease.
Medicinal efficacy: Cod-liver oil is used as a source for essential fatty acids(EFAs) such as omega-3s like eicosapentaenoic acid(EPA) and docosahexaenoic acid(DHA), EFAs could lower blood fats and cholesterol and help reduce risks of certain kinds of cardiovascular disease, reduce inflammation and relieve arthritis and allergies, prevent hazardous clots. It is also applied for prickly heat, diaper rash, and hemorrhoids and prevents skin irritation.
Administration of Cod-liver oil:

Administration Guide of Cod-liver oil
Herbal classic books:
The daily dosage of cod-liver oil supplements is 20 ml, or follow instructions of supplements.
Contraindications, Precautions and Adverse Reactions: The potential risks of taking any fish oil supplement in large doses or over extended periods are not known. No adverse reactions to cod-liver oil supplements are reported in most trials. But taking much fish oil will make toxic amounts of vitamin A and D build up in your system, so for EFAs supplement better also choose another source.
