FARMERS' BULLETIN 663
UNITED STATES DEPARTMENT OF AGRICULTURE
DRUG PLANTS UNDER CULTIVATION
THIS BULLETIN gives general suggestions relativeto 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 speciesand the demand and prices paid for the product.
The market demand for many cultivated plantdrugs is not large enough to justify growing themexcept as small minor crops.
The haphazard production of crude drugs in smalllots of a few pounds usually means a dissatisfiedproducer.
A special knowledge of trade requirements isnecessary in collecting, curing, preserving, and packingdrugs for market.
Most farm products find a ready local market; aspecial market must be sought for plant drugs.
High prices for plant drugs do not insure largeprofits in producing them. Not the price received,but the difference between the cost of productionand the selling price is the important point.
