    In Tung acupuncture the Xia Bai, Lower White, point is located at the same place as the lateral Yaotongxue point. Its indications are much the same, for back pain and sciatica but also tooth pain due to its location on the San Jiao channel. Its proximity to the source point Yuanchi SJ-4 gives it an influence on the bones (Chu, 2015).

    Acupressure points indicated for neck and shoulder pain/injury/arthritis. Radial point also indicated for back pain, gastrointestinal ailments, headache and indigestion. (Salguero & Roylance, 2011, Encyclopedia of Thai Massage)
