Tree spices are important perennial crops obtained from woody plants, where bark, buds, fruits, seeds, or leaves are valued for aroma, flavour, and medicinal uses. Major examples include clove, cinnamon, nutmeg, allspice, star anise, garcinia, and bay leaf, which have supported global trade, traditional medicine, and culinary systems. Their lifespan, suitability for agroforestry, and market demand enhance rural livelihoods, exports, and sustainability. Rich in essential oils and bioactive compounds, they offer antioxidant and therapeutic benefits, while modern processing and value addition have increased their commercial and nutritional importance.
