Efficacy & Actions
Jianjing is a rather special point. If too much force is applied when massaging this point, it may cause hemiplegia, inability to raise the arm, or even fainting – which is why "heavy strike to Jianjing" is a technique in many self-defense and martial arts systems. On the other hand, gentle kneading of this point can relieve work stress, relax stiff neck and shoulders, and unblock the meridians and blood vessels. This point belongs to the Foot Shaoyang Gallbladder Meridian and is the meeting point of the Gallbladder Meridian, the Hand Shaoyang Sanjiao Meridian, and the Yang Wei Vessel. It dispels wind and clears heat, unblocks the collaterals and reduces swelling, moves qi and relieves pain, and unblocks the meridians and resolves depression. It is a commonly used key point for treating neck-shoulder and breast disorders – especially effective for promoting lactation and relieving pain. First documented in Zhenjiu Jiayijing. "Jian" refers to the shoulder; "Jing" means well. Located on the shoulder in a well-shaped depression – hence the name Jianjing (Shoulder Well). It is also known as "Jianjie."
Contraindications
Do not apply excessive force when massaging Jianjing to avoid dizziness, fatigue, inability to raise the arm, or fainting. This point should be used with caution or avoided in pregnant women to prevent miscarriage. Needling should also avoid deep penetration to prevent injury to the lung apex.
