This is an interesting radio show in Spanish about a new Traditional and Alternative Medicine program in Rosario, Argentina that connects urban farming with health clinics:

-the city Dept. of Health buys medicinal plants from small farmers in Rosario's pioneering Urban Farming Program
-Dept. of Health makes those plants available for free at local health clinics. Currently the plants are available as herbal infusions, later they will available also as soaps, oils, syrups, herbal medicines, and other products.

A lot of the medicinal plants they mention I've never heard of--and I thought I had heard of a lot.
