Chewing resin “Sulfur” or “Zhivichka” - this is what larch resin was called in Siberia, it is a Siberian ethnic product used since ancient times in Siberia to clean the oral cavity, teeth, and pleasant coniferous breathing. Siberians knew that resin (sulfur) protects against scurvy and other ailments. And only in the XX century, as a result of many years of research, Irkutsk scientists made sensational discoveries: when chewing larch resin, resinous substances (phytocides, bioflavonoids, etc.) are released that strengthen the human immunity and improve the functioning of all organs. We can say that the "secret" of Siberian health was found.
