• It allows for best food concentration in the intestinal parcel and it promotes respiratory and sinus health. It is too used to comfort menstrual cramps, strengthens our bones, helps heal insomnia, boosts libido, and encourages vascular health. In combination with water, it regulates our blood force. Himalayan Salt is however pre-pollution and without environmental influence. It is indistinguishable in minerals to the old primordial sea with all the minerals and retrace elements our system needs. These normal minerals are indistinguishable to the minerals, which our bodies have evolved with and are too earlier establish existing in the primordial sea.
