Neem, as the internet informed me, is a tree. It's also the subject of a report titled Neem: A Tree for Solving Global Problems
published by the National Academy of Sciences in 1992. Neem is native to India and South Asia, where its products have been used for their medicinal properties in the Ayurvedic tradition for thousands of years. According to those schools of thought, it’s an effective antifungal, antibacterial, and disinfectant. It's also believed to improve liver function, balance blood sugar, and treat skin diseases, particularly eczema and psoriasis, though thousands of all-caps Amazon reviews attest to supposedly transformative experiences after taking neem-leaf tablets to treat cystic acne. Convinced that a good blood cleanse would cure me of all my ills, I ordered a family-size bottle of capsules comprised of neem leaves, soft twigs, and flowers.
