Obsidian, Black, Massage, Scraper
Scrapers: These are used for either:
A. Light scraping on the body to help extract toxic vibrations held in that body area, or
B. For stronger scraping to remove dead skin cells (usually with the skin wet with water or oil) and allow the pores of the skin to breath and release toxins, or
C. For very strong scraping (like the Gua Sha of Chinese Medicine) to forcefully raise out of the body deeply embedded toxins.
An excellent stone for this is an Obsidian Scraper, with the power of Obsidian to extract toxicity to the surface and then absorb that toxicity out of the body into the stone (where it will need to be cleared from later). This extraction function is referred to as the power to “release to the exterior” in DSM.
