Which of the following is a type of energy therapy?

Reiki is a type of energy therapy that focuses on the concept of universal life force energy. In Reiki practice, practitioners use their hands to channel this energy into the patient in order to promote healing, balance, and relaxation. The underlying belief is that this energy can help clear blockages and stimulate the body's natural healing processes.

Aromatherapy, while beneficial for emotional and physical well-being, primarily utilizes essential oils and their scents rather than engaging with the concept of energy transfer. Acupuncture is based on the principles of balancing energy within the body through needle insertion at specific points but is classified under traditional Chinese medicine rather than being a pure energy therapy. Herbal medicine involves the use of plants and plant extracts for healing but does not focus on energy manipulation or the concept of life force energy.
