Do I have to be concerned about pine nut allergies with 5% Sodium Fluoride Varnish?

The resin/rosin used in Vella Varnish is extracted from pine stump wood and not collected from living trees, therefore does not contain tree sap. This source combined with further synthesis during the manufacturing process greatly reduces any adverse reaction to rosin products due to tree nut allergies. However, as with any medical issue, patients should consult with his/her health care provider.
