Charcoal discs for burning resin, herbs and oils. Use inside a heat resistant dish or incense burner dish. Mediums and energy practitioners use  charcoal discs to burn herbs before, during or after their sacred work and connection to energy. Energy work such as mediumship or psychic readings is a sacred practice and at all times should be respected as so. Burning herbs before, during and after this sacred work is important to keep a safe space. The gift of mediumship is how one uses their ability. Using tools such as herbs, charcoal and oils can be a great offering and alignment to higher vibrations to honour the sacred work from heart space and gratitude as your practice.
