A technique used by both yoga and Ayurveda to improve flexibility is Nadi Shodhana (Alternate Nostril Breathing). In this pPranayama practice, herbs can be used to enhance the cleansing and opening effect upon the nadis (channels of energy), which course through the body's muscles and joints, bringing prana, nourishment, warmth, and moisture for better flexibility with less discomfort. The herbs are also thought to cleanse the muscles and joints of inflammation.
Эта пранаяма вместе с трав. растениями используются для улучшения очистительных процессов и открытия нади - энерг. каналов, которые проходят через мышцы и суставы, привнося прану, запитывая энергией, теплом и влагой для лучшей подвижности... также очищают мышцы и суставы от воспалений
Two common herbs used are turmeric and cinnamon bark. Turmeric has analgesic and anti-inflammatory properties and can help you avoid discomfort associated with strength-building postures by reducing the buildup of free radicals that occurs as your muscle tissues consume oxygen; this also reduces postpractice pain and recovery time. Research published in the 1993 Journal of Ethnopharmacology (vol.38) showed turmeric to be a nutrient for connective tissue, stabilizing the collagen fibers and preventing adhesions caused by stress and overstretching.
Traditionally, turmeric is said to provide the energy of the Divine Mother and grant prosperity. It cleanses the chakras, purifies the channels of the subtle body and helps stretch the ligaments and, therefore, is highly recommended for the practice of hatha yoga. Mixed with honey, turmeric can be used externally for sprains and strains. Cinnamon bark is known throughout Asia for its ability to strengthen, warm, and harmonize the flow of circulation into the muscles, joints, and bones. And in the Taoist yoga systems of the Far East, a combination of peony root and licorice root is used to reduce muscle tension.
