The present invention provides an interchangeable multi-purpose healthcare apparatus comprising silicate-based ceramic materials containing tourmaline, said apparatus comprising a cylindrical bottle body (101) and different functional heads for different purposes. A top open end of said cylindrical bottle body is configured with a screw-type bottleneck (103) for connecting different functional heads according to different needs of the user. The present apparatus takes advantages of the far infrared ray, microcurrent and negative ions matching human bioelectricity which are emitted and transmitted by the silicate-based ceramic materials containing tourmaline, in association with the addition of liquids of different temperatures as massage medium, to allow suitable temperature adjustment of the user. Massage medium being functionalized by the tourmaline-containing ceramics can also be beneficial to human body. In combination with different functional heads and auxiliary materials, the present apparatus becomes a personalized and specialized apparatus for massage and auxiliary health care.
