You can wear a gemstone as a necklace, pendant, earrings, or ring. The gemstone you choose to wear depends on what type of energy you would like to use. Amethyst is known to increase psychic abilities while Rose Quartz is to increase love in your life whether that is within yourself or to gain it from another individual. There are so many different gemstones and each and every one of them bring a different property or element into one's life. Personally,I like to wear a malachite ring because the Malachite Gemstone is known to promote spiritual growth, enhance powers for vision, for protection, and to heal stomach ailments.
Cactus, especially the San Pedro, is psyochactive, telepathic, hallucinogenic, and medicinal when it is cooked and digested (drank). Basically, you cut part of the stem and boil it then drain the essences (liquid) from it. For more information about the San Pedro Cactus please visit the link below:
