The benefits of neem oil are multifaceted, ranging from pest control in gardens and agricultural settings to cosmetic and medicinal applications. In gardening, neem oil is used to control fungal diseases and as a natural fertilizer. In health and beauty products, it is valued for its antifungal, antibacterial, and anti-inflammatory properties, making it useful for treating skin conditions, promoting healthy hair, and supporting oral health.
Potential Risks and Side Effects
Despite its numerous benefits, neem oil can have negative effects when not used properly. It can cause skin irritation in some individuals, and its strong smell may be overwhelming. Ingestion of neem oil, especially in large quantities, can be toxic and should be avoided. Neem oil can also interfere with fertility, making it something to be cautious with for individuals trying to conceive.
Places and Situations to Avoid Using Neem Oil
Given the potential risks associated with neem oil, it’s crucial to know where and when its application might be harmful.
