When you walk up to the blooming oleander, you can intuitively feel a special aroma, but don't be greedy for this charming fragrance, oleander and even the pollen are poisonous. Oleander is not native to the continent, their "ancestry" is in the Eastern Mediterranean and is now widely distributed in tropical and subtropical regions around the world.
Oleanders generally grow in a warm and humid environment, for them, sunlight is the best care products, the better the light, the more vigorous the oleander will grow, their flowering period is mainly concentrated in June to October every year, and the fruiting period is slightly later.
Modern toxicology believes that oleander is highly toxic and very toxic. However, the ancients believed that oleander was also poisonous and medicine, and "Luchuan Materia Medica" believed that oleander had the effect of relieving pain and removing stasis and treating epilepsy. In the mainland, oleander is more likely to appear in urban greening, decorating human cities with their whitewashed and jade figures.
Don't look at the beauty of oleanders, they are really poisonous plants. If you want to ask how toxic oleander is, it can be seen from the fact that they can kill people with 10 leaves, and if humans or animals eat oleander by mistake, if its toxicity reaches a certain dose, it will induce life-threatening.
The toxins of oleander are soaked inside and out, they are highly toxic in a living state, and they still have a lot of toxicity after drying, and even the milky white juice that flows out of the branches of oleander also contains toxins.

Why is oleander so toxic?
Whether you see the delicate and gorgeous figure of oleander in the mountains or in the park, it is an incomparable scenery. But behind this beauty, there is the threat of "poison". So, why is oleander so toxic?
This is mainly because oleander contains a variety of cardiac glycosides, as well as toxic components such as triterpene saponins and rubber inositol. In particular, cardiac glycosides in oleander are highly toxic components and are extremely high in leaves. It is reported that the most beautiful moment when oleanders bloom is when they are the most toxic and dangerous.
Despite their beauty, oleanders are poisonous in their seeds, roots, flowers, and milky liquid, and even if they are dried into clumps or incinerated, they are still a deadly deterrent.
What kind of poisoning reaction will occur when ingesting oleander? First of all, because the main toxin of oleander belongs to the late-acting cardiac glycosides, when humans or animals eat it by mistake, it will produce a strong vomiting effect, and then heart arrhythmia, gastrointestinal discomfort and other diseases. Not only that, but it is also quite difficult to treat, and in serious cases, they die before they even have time to be rescued.
Why is oleander, such a deadly nut, still favored and widely cultivated in cities?
It stands to reason that the more dangerous and poisonous things are, the farther away people will be from them. Why are oleanders still so popular and widely planted in urban greenery, gardens and scenic areas? In fact, this is mainly related to the huge benefits of oleander. The first is the economic benefits of oleanders, which are not only pleasing to the eye, but also highly adaptable to the environment, with a high survival rate when planted.
Oleanders are extremely drought tolerant, as well as hardy to a certain extent, and they do not require much soil, so they can easily survive when planted in various urban landscapes.
In addition, the planting and maintenance costs of oleander are relatively low compared to other picky landscape plants. Due to its unique and splendid posture, oleander is also favored by developers of urban scenic spots, believing that its unique beautiful scenery can increase the flow and attractiveness of the scenic spot during the flowering period, and is suitable for making it a good scenic spot to check in. From this point of view, the comprehensive economic benefits of oleander are still quite high, so it is not surprising that it is favored.
In daily life, we see oleander pink and jade in the urban green belt, which can be said to be a frequent visitor to many advanced civilized cities, and the reason why they are obsessively planted in the city by human beings is more because of its ecological and environmental protection. Because of its special physiological structure, oleander has excellent resistance to dust and smoke and the ability to absorb toxic gases, and they are known as "green vacuum cleaners" for their outstanding ecological and environmental protection qualities.
The mystery lies in the oleander leaves, which are dotted with pores on their green leaves, which help them absorb toxic gases and resist smoke and dust, while purifying the air and making the city suffering from air pollution fresh and healthy.
When oleander plays a filtering role, people do not need to worry about overloading and dying of oleander pollution, because the oleander leaves are protected by a tight layer of wax. During the day, all kinds of automobile factory exhaust fumes, automobile exhaust fumes, residential smoke, and urbanization dust permeate the air, obscuring the blue sky a lot, and threatening people's respiratory health. But for these intractable problems, the mighty army of oleanders can be purified in one night, so that citizens can smell the fresh air as soon as they wake up in the morning.
The advantages of oleander do not stop there, the oleander army on both sides of the city's roads not only filters toxic gas and soot, but also plays the important role of "disinfection ambassador". Oleander volatilizes a powerful acrylic component that inhibits bacteria that are raging in the air and acts as a sterilizer. That being said, oleander is highly toxic after all, so remember not to approach it to avoid eating it by mistake.
Oleander is both a "beauty killer" and a "green ambassador", and their presence plays a great role in purifying toxic gases and urban soot. If oleander is applied in the right place, such as as urban greening, then the advantages of oleander can be maximized for people's use, thank you for reading.
