An interesting research study on 21 different plant extracts, including Burdock, and their effects on elastin and collagen, the two key proteins in connective tissue. Both proteins are critical throughout the body but highly noticeable in skin quality, muscle tone, bone strength and the all important arterial wall. Most people who have gotten this far know that skin condition often indicates liver issues. So it’s wonderful to have beautiful skin but perhaps better to have a healthy liver. Bear in mind that these researchers tested “extracts” of the herbs noted here. That means they were concentrates. So for instance, where “white tea” is noted, this does not refer to a simple cup of “white tea” tea, as an infusion, but rather the solvent extract of the white tea plant. The following excerpt is from a study referenced at the bottom of this post and available on the National Institute of Health’s website at https://www.ncbi.nlm.nih.gov/pmc/
Owing to their roles in tissue remodelling in health and disease, several studies have reported investigations on plant extracts as inhibitors of proteinases and as anti-oxidants.
The anti-aging and anti-oxidant properties of 23 plant extracts (from 21 plant species) were assessed as anti-elastase and anti-collagenase activities and in selected anti-oxidant assays along with phenolic content.
Anti-elastase activities were observed for nine of the extracts with inhibitory activity in the following order:
white tea (~89%)
burdock root (~51%)
Anti-collagenase activities were exhibited by sixteen plants of which the highest activity
was seen in:
white tea (~87%)
green tea (~47%)
rose tincture (~41%)
From a panel of twenty three plant extracts, some one dozen exhibit high or satisfactory anti-collagenase or anti-elastase activities, with nine having inhibitory activity against both enzymes.
