TREES AND SHRUBS FURNISHING MEDICINAL BARKS. 9 



When the barks are thoroughly dried and have been broken or cut 

 up into suitable lengths, they may be packed in dry, clean barrels 

 or other proper containers ready for shipment. 



It will be well to repeat here what has been said in the first of this 

 series of papers, entitled ''American Root Drugs," w T ith regard to 

 the advisability of correspondence with crude-drug dealers previous 

 to shipment, in order to ascertain whether a particular drug is desired, 

 how large a quantity is wanted, and what price will be paid. 

 Samples representative of the drug to be disposed of should be sent 

 at the same time. 



It is necessary also to emphasize the fact that the prices given in 

 this bulletin are approximations only, being those paid at the present 

 writing, and it must be remembered that before this bulletin is off 

 the press a drug now listed at 10 cents a pound may have declined to 

 5 cents or less, while a drug quoted at 2 cents may be worth 5 or 10 

 cents or more. The object in noting prices is simply to give pros- 

 pective collectors an idea of the range of prices, but with the constant 

 fluctuations that take place in the drug market it will be readily 

 understood that these prices can be but remotely approximate and 

 that the actual price to be paid can be ascertained only through 

 correspondence with drug dealers. 



TREES AND SHRUBS FURNISHING MEDICINAL BARKS. 



Each section contains synonyms and the pharmacopoeial name, if 

 any, the common names, habitat, range, descriptions of the tree or 

 shrub, as well as of the bark as found in commerce, and information 

 concerning collection, prices, and uses. 



Bittersweet (Solatium dulcamara) is the only one of American 

 medicinal plants of which the young branches alone are used, but it 

 is nevertheless given a place with the barks, as it can more properly 

 be included in this series than in any other.
