Anacardium orientale is a homeopathic remedy made from the marking nut plant. It is used to treat neurasthenia, mental and physical weakness, lack of power, and trembling from overexertion. Symptoms include changing mental states, irresolution, contradictory impulses, and sensations of pressure throughout the body. Aggravation occurs from mental exertion, emotions, anger, and fright. Amelioration comes from heat, eating, and lying down. It is used for nervous disorders, headaches, skin eruptions, digestive issues, and conditions from sedentary lifestyles.
