Re: Article - New insights into phytogenics

From the scientific point of view there are always the same problems with such publications:
1) the exact composition is not mentioned (ingredients and percentage)
2) the definition of plants (crude drug or powder) / extracts / essential oils is either missing or unclear, sometimes (semi)synthetic nature-identical substances are used and declared as essential oils or extracts
3) quality data = phytochemical data of the plants/extracts/ess. oils are missing: at least the chemotype of the material and the percentage of the main compounds

Due to that no clear relation between substance and effect can be drawn! Most of such publications are therefore nice scientifically decorated (veiled) advertisements.

Re: Article - New insights into phytogenics

Your comments hold true, although production will adopt to scientific trends with practical successes much faster than science can prove. These ingredient technology trends will lead to similar animal responses across product and geographical variances, convincing me there is not one single phytonutrient or blended ingredient product for all practical challenge and bio-burden variations at the animal production level.
