I constantly tell people "do not buy Herbal remedies off the shelves and without a proper consultation and it should be under proper supervision". This is why we have a 90 minute initial consultation, to check every system in your body, diet and lifestyle.
All 'Practitioner Only Products' are tested in labs to ensure it is the correct medicinal herb (a lot of plants can look and feel similar but they are not), quality and efficacy. Qualified Practitioners are monitored by the companies ensuring we are properly dispensing and have technical support just a phone call away.
Just as there are different varieties of apples there are different varieties of the same herb and not all are medicinal.
A Timely reminder DO NOT SELF MEDICATE with Herbal supplements.
