I'm sorry for any confusion, but "Santalaceae" is actually a botanical term referring to a family of flowering plants, also known as the Santalaceae family. It is not a medical term. The Santalaceae family includes several genera of trees, shrubs, and climbers, many of which have aromatic properties. Some well-known members of this family include sandalwood (Santalum album) and mistletoe (Phoradendron spp.).

If you're looking for a medical definition or information, could you please provide more context or clarify your question? I'm here to help!
