Papier d'Armenie
Papier d'Arménie (Armenian paper) is a type of paper incense or room deodorizer that has been produced in France since 1885. The paper is soaked in a solution of benzoin resin that has been dissolved in alcohol; with varieties, such as Rose, which have additional fragrances or essential oils.
Papier d'Arménie was developed in the late 19th century by a French chemist, Auguste Ponsot, who, after visiting Armenia where he saw the locals burning benzoin resin to refresh and cleanse their homes, created the incense paper with pharmacist Henri Rivier. The recipe and method of production is a trade secret.
There are variations, such as Carta d'Armenia which is sold by Santa Maria Novella in Italy, and Carta Aromatica Eritrea.
