”Dr. Hess Poultry Inhalant: A Spray" Dr. Hess & Clark, Inc. Brown glass, round bottle.
This is a bottle of Dr. Hess Poultry Inhalant, an aid for clearing mucous from the respiratory tract in chickens. It's also marketed as effective against bronchitis. One 2 oz. bottle could allegedly treat 100 adult birds (or 200-300 chicks). In 1945, one of these vials would sell for 39 cents, as seen in advertisements at the time. Dr. Hess & Clark, Inc. was located in Ashland, Ohio.
Directions on the bottle instruct the user to add 1 tablespoon of the inhalant to 1/2 pint of water in a clean sprayer, discharging a fine mist. One must shake the mix thoroughly before spraying the birds in a confined space. It advises to apply the spray at 1 to 3 hour intervals throughout the day. It also lists instructions on how to apply the inhalant to hogs.
Ingredients include: pine oil, eucalyptus oil, camphor oil, castor oil soap, guaiacol, and beechwood creosote (which today, in the form of guaifenesin, is used to clear mucous).
