Cassava is one of the three largest potatoes in the world (cassava, sweet potato and potato). There are more than 100 varieties of cassava, among which cassava is the only one used for economic cultivation, and the others are wild varieties. Cassava can be divided into sweet and bitter varieties.
The annual world trade volume of cassava accounts for about 10% of the total output, and the main products are dried slices, granules and cassava starch. China, Japan, the United States and other countries are the main importers of cassava products in the world, accounting for about 70 ~ 80% of their total trade. Thailand is the largest exporter of cassava products in the world, and other major exporters are Indonesia and Vietnam. Overview of medicinal materials
Drug Name: Cassava
Source: cassava leaf, a dicotyledonous plant medicine Euphorbiaceae.
Efficacy: detumescence and detoxification.
Indications: used for carbuncle, sore, swelling and pain, traumatic injury, traumatic swelling and pain, scabies, stubborn tinea and other diseases.
Sexual taste: bitter, cold. This species of Heart Meridian is a poisonous plant included in China Botanical Atlas Database, and its toxicity is the whole grass, especially the fresh root tuber. There are many reports of cassava poisoning. Symptoms of poisoning are mild, such as nausea, vomiting, diarrhea and dizziness. In severe cases, dyspnea, rapid heartbeat, dilated pupils and even coma occur, and finally convulsions, shock and death are caused by respiratory failure. It can also cause chronic diseases such as goiter, fatty liver, optic nerve and motor nerve injury.
Administration and dosage: oral: decoction, 3-6g. External use: apply proper amount to the affected area, or grind it into powder for oral administration.
Distribution of animal and plant resources: Fujian, Taiwan Province, Guangdong, Guangxi, Guizhou and Yunnan are cultivated.
Latin name: cassava.
English name cassava[k? sū:v？ ]
Examination: First published in Xinhua Materia Medica.
Root toxicity:
Cassava tubers are poisonous and must be soaked.
Be careful when eating cassava. The toxic substance contained in cassava is linseed picroside. If you ingest raw or uncooked cassava or drink its soup, it may cause poisoning. The reason is that flaxseed picroside or flaxseed picrosidase produces free hydrocyanic acid after gastric acid hydrolysis, which makes people poisoned.
If a person eats 150 ~ 300 grams of raw cassava, it will cause poisoning and even death. In order to prevent cassava poisoning, peel cassava before eating it, and soak potato meat with clear water to dissolve cyanosides. Generally, soaking for about 6 days can remove 70% of cyanosides, then heating and cooking before eating.

Due to the transfer of rural labor force, land lease, merger and other forms of circulation, coupled with labor shortage and rising labor prices, there has been an intensive and mechanized farming trend in which processing enterprises and large planters unite to concentrate on contiguous development. Cassava raw materials are in short supply day by day, and the production base is expanding abroad.
Suggestions for the development of cassava industry 2011;
Vigorously support infrastructure construction. Focusing on the development of cassava industry, we will increase investment in cassava production infrastructure, focus on strengthening the construction of base facilities such as production and improved seed breeding, encourage enterprises and various service institutions to participate in the construction of cassava production bases and improved seed and seedling bases, and establish modern cassava production demonstration zones based on industrial advantages. According to the needs of cassava industry development, we will constantly improve financial support policies, increase subsidies and broaden the scope of subsidies. Establish a demonstration base for high-yield and high-quality seedlings and implement subsidies for the construction of cassava production bases. Actively participate in international and regional exchanges and cooperation. Consolidate and improve the mechanism of bilateral international cooperation and exchange, and actively expand new communication channels. Intensify the introduction of foreign new varieties, advanced technologies, management experience and funds, guide and support domestic scientific research institutions and enterprises to carry out foreign cooperation and exchanges and explore the international market, give necessary policy support in financing, insurance, foreign exchange receipts and payments, and do a good job in supporting services. Improve and strengthen the service function of finance to support the development of cassava industry. Improve the linkage between production and marketing and market monitoring mechanism, and promote the establishment of long-term, stable, mutually beneficial and cooperative production and marketing relations between the main cassava producing areas and marketing areas. Actively cultivate and expand the leading enterprises of cassava industrialization, vigorously develop professional cooperative economic organizations, improve the degree of industrial organization, and promote the reform and innovation of internal systems and mechanisms of relevant agricultural reclamation enterprises. Cassava Cassava is one of the three largest potatoes in the world and is widely planted in tropical and subtropical regions. Cassava is the fifth largest crop in the south subtropical region of China after rice, sweet potato, sugarcane and corn. It plays an important role in crop layout, feed production and industrial application, and has become the main processed starch and feed crop widely planted. Cassava is the root tuber of Euphorbiaceae, which is conical, cylindrical or spindle-shaped, fleshy and rich in starch. Cassava flour is of good quality and can be eaten, or used in industry to make alcohol, fructose and glucose. All parts of cassava contain cyanoside, which is toxic. The fleshy part of fresh potatoes can only be eaten after soaking and drying. Because fresh potatoes are perishable, they are generally processed into starch, dried slices and dried potato granules as soon as possible after harvest. There are two main types of cassava: bitter cassava (specially used to produce cassava flour) and sweet cassava (eaten in a way similar to potatoes). Processed and eaten, it is one of the main miscellaneous grains of local residents.
Cassava tuberous root is not a balanced food, because most of cassava dry matter is starch, which contains about 25% ~ 30% in fresh potatoes and about 80% in dried potatoes. Cassava tuber contains less nitrogen, which is 1.5% ~ 4%, of which about 50% is non-protein nitrogen, mainly nitrite and nitrate nitrogen. In the amino acid composition, lysine and tryptophan are relatively more, but methionine and cystine are lacking. Cassava tuberous root has low crude fiber content (1% ~ 2%), low fat content, high calcium and potassium content and low phosphorus content, and contains phytic acid and a small amount of vitamin C, vitamin A, vitamin B 1 and vitamin B2. Cassava is mainly used as food and is the largest food crop in developing countries in tropical areas.
