Whether the succulent plants are poisonous

Recently, the Internet began to spread the news that “succulents will be illusory, don’t raise them.” This is undoubtedly a fatal blow to friends who love “succulent”. So, is all “succulent” toxic, or is it only a part of succulents that are toxic?

Toxic “succulent” is not okay, it will be fine.

It is often said that succulents, in the plant kingdom, do not refer to a single group of families, but are a general term for a class of plants that have a succulent and succulent character on the vegetative organs of stems or leaves. According to statistics, common succulents come from at least 25 families, such as Rosaceae, Cactaceae, Apricot, Sedum, etc., nearly 10,000 kinds of succulents in the world.

The Shangguan Fazhi, a museum engineer at the Kunming Institute of Chinese Academy of Sciences, has long been concerned with the study of plants and their toxicity. He said that succulents such as the silver-crowned jade are the cactus family, which is native to western North America. This genus contains an alkaloid called “Meskaring”, so it is also called a poison cactus by the meat lovers. After taking this alkaloid, it will affect people’s hearing and visual experience for a short time, which will cause hallucinations. It is a plant-like hallucinogenic drug. Excessive or long-term intake is indeed a great risk.

In addition to the silver crown jade, there are some genus succulents that have potential toxicity risks and must also be noted. For example, the white juice of most succulents in Euphorbiaceae is poisonous. White sap in stems and leaves such as unicorn, cloth, keel, and bachelor will cause redness, itching and other allergic symptoms.

The succulents of the genus Rosaceae are generally not easy to provoke, and their white milk is often toxic and unfit for human consumption. In addition, in the agave, sedum and cactus plants, some species of juice, burrs can cause itchy skin, dermatitis and some allergic symptoms.

But even so, people do not have to worry too much about succulents. Toxic succulents are only “niche”, and most of their toxic substances are alkaloids. They are not volatile. As long as they are not imported, they are generally not healthy. risk. If the skin is inadvertently exposed to the plant juice, wash it with water in a timely manner. Some succulents that may pose a health risk should be kept away from children and pets to avoid eating.

Many “more meat” have medicinal value

In fact, meat is not only a hallucinogenic poison, and some have the power to cure diseases. China has a large number of high-value succulents, many of which have medicinal value. For example, aloe vera is recognized as the most widely used medicinal succulent plant. It has hundreds of species. According to the literature, aloe vera can treat sputum, hemorrhoids and burns, cuts, abrasions, frostbite, lacerations, etc. without scars, because it is rich in aloe vera, aloe-emodin and various amino acids and vitamins. It is also effective for constipation, acne, stomach ulcers, tuberculosis and high blood pressure, and is widely used in the cosmetics, food and pharmaceutical industries. In addition, the spines of the cactus plant with less flesh and thick stalks, external application after peeling and smashing, can cure skin diseases such as sputum, the Jinwu fan and the sword palm in the genus also have obvious curative effect on mumps; Rhodiola rosea, Vasson, has been a plant for both medicine and food since ancient times.

In addition, some exotic cultivars or wild succulents are also of great practical value. For example, pear fruit cactus can be used as wild fruit, agave can be used as fiber material, and apricot and sunflower can be eaten as vegetables. However, experts caution that it should be used after a clear understanding of the succulent varieties and characteristics of the planting, to avoid ingestion of poisoning or other adverse consequences due to identification errors.

Entry into the “succulent” requires quarantine

Due to the large number of breeding and breeding at home and abroad, new varieties of succulent plants are emerging every year. They should be selected according to their own preferences and planting conditions, but they should be planted in places with sufficient sunlight and ventilation. If the space is small, you can choose the “slaughter” with smaller body size; if the light environment is insufficient, you can choose the variety that is resistant to yin; if the local climate is humid, sultry and rainy, you can choose heat and humidity. At the same time, when purchasing succulents, consumers should purchase as much as possible from regular businesses and large professional flower markets. They should not “sea tao” succulent plants and seeds.

If you purchase or carry succulents directly from overseas, you need to meet the requirements of the “List of Animals and Plants and Their Products and Other Quarantine Objects Prohibited to Be Carried and Mailed into the People’s Republic of China”, seeds, seedlings, seedlings and other reproductive capacity. If plant materials and organic cultivation media are listed on the forbidden zone, import is prohibited. Animals and plants, their products and other quarantine objects that are imported or mailed by the State, are subject to the approval of the relevant national administrative authorities, and have quarantine certificates issued by the official agencies of the exporting countries or regions, which are not subject to this list.

The succulent plants that have not been approved by the Chinese inspection and quarantine department may carry various kinds of seeds, insects, germs and other harmful organisms, thus threatening the safety of our country and having the risk of breaking the law. In addition, many succulents are also not allowed to import or export under the Convention on International Trade in Endangered Species of Wild Fauna and Flora or the Wild Plant Protection Regulations.
