Yes, it is good. More of an alert feeling. Not taking tincture of natural l-dopa as often. Memory better. I know we absorb just about everything that touches our skin. Gently massaging this combination on face , neck and shoulders and back of neck ( a mixture of 1 teas turpentine and 1/4 C castor oil.) Just keep it away from nose and eyes. Using Diamond G Forest 100% pure turpentine. I am anxious to try on sugar cubes internally, but my bowels are not moving well enough yet...still working on them, but do think this mild , even minute dose topically is helping. Will keep you all informed. Aunt Bean
