Nerium oleander | Functional Uses and Benefits
Permalogica cannot take any responsibility for any adverse reactions or health effects from using plants. Always consult a professional before using plants for medicinal purposes.
Edible: No
Medicinal: Historically used medicinally, but highly toxic and unsafe for self-medication. Modern science only studies it under strict laboratory isolation (like the compound oleandrin).
Cosmetics: Commercially used in patented anti-aging skincare lines (such as NAE-8 extract) and studied for topical acne treatments.
Animal Feed: Not suitable; highly toxic to livestock and pets
Fiber: Limited use from stem fibers
Timber: No significant timber value
Firewood: No – toxic smoke may be produced when burned
Wind Break: Yes – effective due to dense evergreen growth
Fence: Yes – commonly used as a living hedge or screen
Cover Crop: No
Mulch: No
Nitrogen Fixer: No
Dynamic Accumulator: No confirmed data
Pollinator Attractor: Yes – flowers attract bees, butterflies, and other insects
