Your question is as legitimate as it is complex! For years I have been “fighting” for the transparency of products, especially herbal and natural ones. Let’s say that a “serious” herbal product should be “standardized”. It must contain and guarantee the uniformity in percentage of the active ingredient contained therein. The origin and derivation (organic product) should be indicated. In the composition, we will have to be able to read only natural components inherent to the specific herb or plant. The more “elements” there are, the less the product is pure or of good quality. Many excipients exist to make up the tablets or lozenges. The sugarsand sweeteners to make syrups tastier and so on. Unfortunately, very few companies have the foresight to indicate the crops and regions of origin. From experience, the less “commercial” companies at the expense of those known and therefore advertised, give more guarantees. He should contact the companies directly for the relevant information, but sometimes the information is “piloted”. However, beyond all, the best thing is to “inform yourself” about the manufacturing processes of herbal preparations. Once this is done, he will realize how great is the “deception” we are subjected to on a daily basis. Most of the companies then, do not produce, but rely on other companies by simply changing the brand, tweaking the percentages or ingredients. Even pharmacies and herbalists are used to this procedure. “You can also buy our cream or our syrup … we do it” … NB: the law allows the production “in house” only in the face of an “oc” laboratory approved by ASL with all the expensive hygienic characteristics santario and related controls. Not to mention the “ignorance” of users but also of the buyers themselves who trust suppliers trained to flaunt the word “natural” and “organic”. At the end of the month, the book “the food that goes through my head” is available on amazon, where all this is extensively covered. Greetings the law allows the production “in house” only in front of a laboratory ad “oc” and approved by ASL with all the expensive hygienic and sanitary features and relative controls. Not to mention the “ignorance” of users but also of the buyers themselves who trust suppliers trained to flaunt the word “natural” and “organic”. At the end of the month, the book “the food that goes through my head” is available on amazon, where all this is extensively covered. Greetings the law allows the production “in house” only in front of a laboratory ad “oc” and approved by ASL with all the expensive hygienic and sanitary features and relative controls. Not to mention the “ignorance” of users but also of the buyers themselves who trust suppliers trained to flaunt the word “natural” and “organic”. At the end of the month, the book “the food that goes through my head” is available on amazon, where all this is extensively covered. Greetings users but also the buyers themselves who trust suppliers trained to flaunt the word “natural” and “organic”. At the end of the month, the book “the food that goes through my head” is available on amazon, where all this is extensively covered. Greetings users but also the buyers themselves who trust suppliers trained to flaunt the word “natural” and “organic”. At the end of the month, the book “the food that goes through my head” is available on amazon, where all this is extensively covered. Greetings
