​Why do we still plant oleander if it is poisonous

Oleander is planted in many places in rural areas, for example, beside fences and roadsides, where it is used for decoration and greening. However, oleander is a poisonous plant. Pregnant women in particular must stay away from oleander because the juice of oleander flowers can cause miscarriage. However, oleander also has cardiotonic and diuretic effects. So why plant it if it is poisonous? Let me introduce it to you below.

1. Purify the air

The leaves of oleander have strong adsorption properties and have strong absorption and purification capabilities for carbon dioxide, sulfur dioxide, dust, etc. in the air. Planting oleander in parks, scenic spots and other places is very beneficial to human health. With the strengthening of environmental awareness, oleander is now planted on both sides of the road to help digest automobile exhaust and other harmful substances.

2. Ornamental value

Oleander is propagated by cuttings, so it rarely bears fruit. The flowering period is longer than that of many plants. The cultivated oleander blooms almost all year round and has a high ornamental value. There are fewer flowers in summer and autumn, but oleander flowers are very beautiful. Planting a patch of oleander flowers can avoid the monotony of the city's summer and autumn scenery and is suitable for gardening.

3. Vitality

Oleander can be propagated by cuttings and layering. The simple planting method is suitable for mass planting, so oleander is more common in urban green belts and roadsides. Even if it is covered with dust and other toxic substances, oleander can still grow vigorously and has very tenacious vitality.

4. Used as medicine in traditional Chinese medicine

Oleander is toxic because of the linalool in it. With the exquisite combination of traditional Chinese medicine, oleander is used as a medicine, which has the effect of strengthening the heart and diuresis. Oleander can be used as a traditional Chinese medicine to treat heart disease, enhance the contractility of myocardial fibers, and can also be used to treat injuries from falls.

5. Other Values

1. Oleander fiber has a certain toughness. After extraction, it becomes an excellent quality textile raw material and can be made into exquisite textiles.

2. Oleander seeds contain about 60% oil, and the oil extraction value is high. However, oleander seeds are somewhat toxic and cannot be eaten. After extraction and processing, they can be used to make industrial lubricants.
