Juan 1 Wind Disorder, section 17: Symptoms of bi and the lack of movement in the limbs caused by wind
風寒濕三氣合而為痺。風多者為風痺。風痺之狀，肌膚盡痛。諸陽之經，盡起於手足，而循行於身體。風寒之客肌膚，初始為痺，後傷陽經，隨其虛處而停滯，與血氣相搏，血氣行則遲緩，使機關弛縱，故風痺而復手足不隨也。其湯熨針石，別有正方，補養宣導，今附於後。
The combination of these three qi – wind, cold and damp, creates bi. When wind predominates, it creates wind-bi. The signs of wind-bi are that muscles and skin become extremely painful. All the yang channels begin in the hands and the feet, and run their courses through the body. Wind-dampis lodged in the muscles and skin. At the outset, it creates bi, injuring the yang channels and following them to where there is a deficiency. It then stops and becomes stagnant. It attacks both blood and qi, so that they become sluggish, and the gateways (between the joints) are no longer under control. Hence, it causes recurrence of wind-bi and a lack of movement in the limbs. The orthodox prescription for decoction, hot pack, needles and stones is given elsewhere. The yangsheng supplementation and daoyin instructions are now attached here below.
《養生方‧導引法》云︰左右拱兩臂，不息九通。治臂足痛，勞倦風痺不隨。
The Yangsheng Recipes: The Daoyin Methods says, ‘Make an arch with left and right arms and hold your breath. Do this nine times. It cures pains in the arms and legs, exhaustion and tiredness, and lack of movement caused by wind-bi’.
