Thai herbal ball massage is a type of hot treatment, which means herbal balls must be handled with care after removing them from the steamer and the therapist must always test their temperature before applying them to the client's body. Once they can be used safely, five basic techniques can be employed with Thai herbal balls: rocking, rolling, stamping, dragging, and stationary pressing. The most common Thai herbal ball massage involves rocking and rolling the balls while applying steady pressure, perpendicular to the treated area.
