Citrine is said to be a powerful healing quartz - good for solar plexus work; mental and emotional clarity, problem solving, memory, willpower, optimism, joy, confidence and self-discipline. It is used to reduce anxiety, fear, depression, stomach tension, food disorders and allergies. It is also thought to enhance the body's healing system and tissue regeneration. Citrine attracts abundance and the ability to manifest. Beautiful and useful too! Pendulums are used much the same way as applied kinesiology or muscle testing to help determine the answer to a question.
