J. Dis. Immediate medical attention must be sought for reactions that occur during or after leaving physician’s office.

The extract is a sterile solution containing extractables of source materials obtained from biological collecting and/or processing firms and Antigen Laboratories. 6 10 It is also used sometimes for bronchitis, coughs, and sore throat; for colic; and for congestion in the liver. A negative control, 50% glycerine diluted with diluent to 5-2 (1:25) or 10-1 (1:10) dilution and a positive control of histamine phosphate, should be tested and included in interpretation of skin reactions.1, 13. Orris root powder is still used extensively in potpourris, sachets, and pomanders. A 5/8 inch, 25 gauge needle on a sterile syringe will allow deep subcutaneous injection.
