On The Question Of Environmental Impact Of Exotic Herb Use

Although chocolate consumption has been heavily promoted in the recent years by health authorities and enthusiasts alike, it may not be the solution to the modern health problems if environmental consequences are to be taken into account. As suggested by a study conducted in Germany, high consumption of stimulant foods, such as tea, cocoa, coffee, and wine, leads to an unbalanced “virtual land use” – a measure of food sustainability on a national level. Reduction of consumption of these items together with following the officially recommended diet would ameliorate the problem. On the other hand, a switch to lacto-ovo-vegetarian or vegan diet would result in positive balance, even without dodging the stimulants.

This brings up an interesting perspective of viewing nature and health as two intrinsically connected properties. Unfortunately, this vision is not fully represented in modern health movements. The reason for this is, perhaps, the high degree of differentiation between scientific disciplines. Scientists study their single area of discipline, rarely connecting between each other. The mindset of our brightest ones affects the society in general. Hence, we often forget to look at the other end of the stick, even when caring for the greater good. We should be mindful of this broader perspective even – and especially – when we are looking to take care of ourselves.

Serum Metabolites Of Plant Extracts Decrease Hepatic Lipid Synthesis

A recently published research paper provides an example of use of an original experimental model. In this study, human hepatic cells were treated with serum metabolites of proanthocyanidin-rich extracts of cocoa, French maritime pine bark, and grape seed administered to rats. All groups of metabolites reduced lipid synthesis by the cells, including that of free cholesterol, cholesterol ester, and triglycerides. In particular, the grape seed extract metabolites reduced the lipid synthesis more so than the extract administered to the cells directly (Abstract).

This study is interesting for the reason that it appears to use an original research model, using metabolites of plant extract to be administered to cells in vitro. The preponderance of in vitro research to date appears to largely ignore the metabolic fate of plant compounds administered to both humans and animals. The compounds or preparations are applied to the cells directly and the effect is observed. This, however, may generate data that is incompatible with real-life circumstances, since ingested compounds rarely enter the blood – and, hence, all the internal tissues – unmetabolized. It may be painful to acknowledge that, because of this, the usefulness of most of the in vitro data to date is limited. In this study, the scientists found an original, if not to say, smart, way to circumvent this problem without having to perform costly pharmacokinetic experiments and synthesis of new molecules. We congratulate them on their ingenuity.

Contrary to what was expected, although there was a large number of studies published on PubMed on this date, most of them were of fairly low significance, and we decided not to devote a special mention to them. For your record, all studies are also entered in the Alphabetical Herbs page (including those that are not mentioned in daily updates), so if you are interested in a particular herb, you can always go there and check the full list of studies.

We did find one study worthy of separate mention: It reports on important biological activities of a compound from Centella asiatica (gotu kola). See below.
