polished aventurine crystal
Aventurine benefits the thymus gland, connective tissure, and nervous system: it balances blood pressure and stimulates the metabolism, lowering cholesterol and preventing arteriosclerosis and heart attacks. It has an anti-inflammatory effect and helps ease skin eruptions and allergies, relieves migraine headaches, and soothes the eyes. Aventurine heals the adrenals, lungs, sinuses, heart, and muscular and urogenital systems. As an elixir, it relieves skin problems.
