On the left side of the sternum is the point for Riboflavin or Vitamin B2.
It plays a major part as a metabolism catalyst in the process of energy gain from fats, carbohydrates and amino acids.
This point needs to be rarely massaged — mainly in patients with a generally weak digestion, gastro-intestinal problems and children with growth problems.
Vitamin B2 deficiency tends to result in skin and mucous membrane diseases and often results in damaged eyes (particularly of the retina), and it is likely, therefore, that the RNA point (between the eyes) tests additionally weak and this point has to be treated before.
Both points should be massaged with a Beryl stone or a Tanzanite.
