Neem oil, derived from the seeds of the neem tree (Azadirachta indica), has been used for centuries for its various medicinal and therapeutic properties. Apart from its well-known applications in agriculture and personal care, neem oil finds several external uses:

1. Skin Care: Neem oil is renowned for its ability to soothe and moisturize the skin. It’s often used in soaps, lotions, and creams to address various skin issues such as acne, eczema, psoriasis, and fungal infections. Its anti-inflammatory and antibacterial properties make it particularly effective against acne.
2. Hair Care: Neem oil is used in hair care products such as shampoos and conditioners due to its ability to nourish the scalp, promote hair growth, and combat dandruff and other scalp conditions. It helps in maintaining scalp health and preventing hair loss.
3. Insect Repellent: Neem oil is a natural insect repellent and is commonly used in the formulation of insect sprays, lotions, and candles. It acts as a deterrent against mosquitoes, fleas, ticks, and other biting insects.
4. Wound Healing: Its antiseptic and antibacterial properties make neem oil useful in promoting wound healing. It can be applied topically to minor cuts, scrapes, and burns to prevent infection and accelerate the healing process.
5. Scabies and Lice Treatment: Neem oil is effective in combating scabies and lice infestations. It can be applied topically or added to shampoos to eliminate these parasites and soothe irritated skin.
6. Pet Care: Neem oil is used in pet care products such as shampoos, sprays, and powders to repel fleas, ticks, and other pests from pets’ coats. It also helps soothe skin irritations and prevent fungal infections in pets.
7. Gardening: Neem oil is a popular organic pesticide in agriculture and gardening. It controls a wide range of pests including aphids, mites, whiteflies, and caterpillars while being safe for plants, beneficial insects, and the environment.
8. Wood Preservation: Neem oil is sometimes used as a natural wood preservative to protect wooden furniture and structures from termites, fungi, and other pests. It helps extend the lifespan of wood without harmful chemicals.

When using neem oil externally, it’s essential to dilute it properly as it can be quite potent in its pure form and may cause irritation in some individuals.
