The pencil cactus is no simple plant; its sap is its secret weapon

There is a succulent that relatively few people grow, with bare branches and toxic sap; this plant is called the pencil cactus. Some people do grow it in pots, but not many, because there have been cases of gardening enthusiasts being poisoned by growing the pencil cactus.

The branches of the pencil cactus are plump and fleshy, very cute. A gardening enthusiast's child was only one or two years old, exactly at the age of being curious about everything and putting whatever they grab into their mouth. Sure enough, upon seeing such a tender green, thick plant, the child grabbed it and bit it, and as a result was rushed to the hospital.

It is not only children; pets can also accidentally eat this pencil cactus, leading to diarrhea, listlessness, and in severe cases it can even be fatal.

The pencil cactus, scientific name Euphorbia tirucalli, is also known as the green coral. It originated in arid regions, and to reduce water evaporation its leaves gradually degenerated, or even disappeared. Because of its peculiar tree shape, with no thorns and no leaves, it is called the "pencil cactus".

The sap of the pencil cactus has the effect of promoting tumor growth, causing cancer by inducing chromosomal rearrangements in human lymphocytes. If it comes into contact with the skin it causes redness and swelling, and if it accidentally gets into the eyes it can even cause temporary blindness. Its toxicity can even kill fish, and in humans, accidental ingestion causes diarrhea in mild cases.

However, if we simply grow it for ornamental purposes there is no danger, but if there are children or pets at home it is recommended to place it somewhere out of their reach.
