Buying Banisteriopsis caapi leaves, often referred to as the "Vine of the Soul," is common for botanical collection and spiritual research. While the vine's woody stem is the most famous part, the leaves are also sought for their specific alkaloid profile and traditional uses.

Different "colors" or varieties of the vine often correspond to the properties of their leaves:

: Most international retailers vary significantly in terms of minimum order quantities and bulk pricing for research materials.

: Sells dried Peruvian caapi leaves ethically harvested by local partners in Peru.
