Native to Asia, the Bitter Orange tree is widely cultivated in China and in the Mediterranean regions. Rich in virtues, its leaves are well known for their beneficial action on the respiratory tract.

With their draining and purifying properties, Bitter Orange leaves help to relieve the respiratory tract by evacuating the toxicities that clog it. Thus, they encourage the expulsion of mucus and soothe bronchial sensitivities to allow optimal respiratory comfort.
