Traditional knowledge: Indigenous communities living in rainforests often have extensive traditional knowledge about the medicinal uses of plants. This knowledge can be invaluable in identifying potential medicinal plants.
Favorable environmental conditions: Rainforests provide ideal environmental conditions for plant growth, including high humidity, abundant rainfall, and warm temperatures. These conditions promote the production of bioactive compounds in plants, which are often responsible for their medicinal properties.
Presence of medicinal plants: Numerous studies have documented the medicinal properties of plants found in rainforests. For example, the rainforest plant rosy periwinkle (Catharanthus roseus) has been used to develop drugs for treating childhood leukemia and Hodgkin's lymphoma.
