FARMERS' BULLETIN 663
UNITED STATES DEPARTMENT OF AGRICULTURE
DRUG PLANTS UNDER CULTIVATION
T
THIS BULLETIN gives general suggestions relative to the culture, harvesting, distillation, yield, marketing, and commercial prospects for drug plants. Specific information is also given concerning the cultivation, handling, and yield of individual species and the demand and prices paid for the product.
The market demand for many cultivated plant drugs is not large enough to justify growing them except as small minor crops.
The haphazard production of crude drugs in small lots of a few pounds usually means a dissatisfied producer.
A special knowledge of trade requirements is necessary in collecting, curing, preserving, and packing drugs for market.
Most farm products find a ready local market; a special market must be sought for plant drugs.
