Herbs
Herbal medicine is itself a powerful method of healing. Western drugs often control symptoms, but do not alter the disease process. Chinese herbs treat the underlying condition as defined by traditional diagnosis, and rarely cause adverse side-effects.
Just as soil depletes through overuse, Qi, Moisture, and Blood are eroded by overwork, emotional tension, mental strain, inadequate exercise, diet, and rest.
Since fatigue results from a lack of Qi, herbs that nourish the Qi have an energizing effect. Since blurry vision, restless sleep, and irritability result from depleted Blood, Blood-enriched bergs improve vision, sleep, and equanimity. Dry skin and dehydration arise from insufficient Moisture, and herbs that replenish it soften the skin and relieve the thirst.
