There is different points of view when it comes to mediums within reflexology. Over the last 12 years I've tried all sorts and now happy with oils that are high saturated or unsaturated ie coconut, olive and sesame. People should use what suits them.
The attitude of some reflexologist that it is not a foot massage is to make it more wow. I prefer to see reflexology as a combined foot massage and micro pressure point energy healing system that considers the feet as a reflection of the whole body.
Not forgetting that in some countries/states a reflexologist might not use a medium so they don't have to have a massage licence.
Why include massage? Because it is an effective form of healing that helps to build a rapport with the client, smoothes the nervous system, increases the flow of blood, lymph and Qi (Chi) both locally and throughout the body.
After many years of practising reflexology, I came to the conclusion that foot charts have there place but are generally rubbish; the intention to heal is paramount - energy follows thoughts - compassion in action; as in any form of healing whether surgery or reflex - the underlining ritual promotes the healing process; and if the feet are considered the microcosm of the whole body - any physical correction to the structure of the feet will provide balance/correction (homeostasis) to the whole body. Everything I have said can of course apply to hand, facial and ear reflexology. This may be this explains how different charts and methodologies seem to work.
