Homemade Thyme Leaf, Rosemary Leaf and Licorice Root Extracts

5 comments
Last month I've made a research about "acne treatment" products and find out that many of them contain:

Thyme Leaf, Rosemary Leaf and Liquorice (Licorice) Root Extracts.

These herbs include essential oils, tannins, flavonoids, saponins, glycosides, phenolic compounds, polysaccharides and triterpenic acids, providing antibacterial and antiseptic action helping to heal the skin and protect skin from acne.
Most of these components can be extracted by Alcohol and Hot Water. The polysaccharide compounds need to be hot water extracted. The anti-inflammatory compounds (triterpenoids) can only be extracted by alcohol.


So we are going to mix the solvent.
Instructions:
Fill a glass bottle (100 ml) with the dryed Thyme Leaves, add a little bit of boiling water (30ml), shake it well, add Vodka to cover the herbs (60ml). After two weeks filter it, and that's all, our Thyme Leaf extract is ready to use. Rosemary and Liquorice was extracted the same way, but the last one was on the ratio 40ml:50ml (Hot Water and Vodka).

*I've prepered my "Lush Inspired - Spot cleanse acne prone skin" on the basis of the Thyme Leaf and the Rosemary Leaf Extracts. Witch Hazel Alcohol Extract I've bought at a local drugstore, but I'm sure it can be made at home as well.


Edited to add:
I found an interesting research "Extraction of Glycyrrhizic Acid and Glabridin from Licorice" published in "International Journal of Molecular Sciences" in 2008 (2008, 9, 571-577) - click to download a full article - and their conclusion about the best method of extraction was:

"In this study, a simple and convenient method for the extraction of glycyrrhizic acid and glabridin from licorice is developed and validated. Mixture of ethanol/water (30:70, v/v) and extraction time 60 min under 50°C is the optimum condition to extract GA and glabridin from licorice. The extracted amounts are 2.39 and 0.92 mg/g and recoveries are 89.7% and 72.5% respectively."

So the best way to extract Licorice Roots using 40% Vodka will be a mixture of 3 part Vodka and 1 part Water, heating during 1 hour under the temperature 50°C.

And another study published in "Dermatology Times"(1 may, 2010): ""using glycyrrhizic acid, the herbal extract from licorice, proves to be effective in halting hair growth in rats. This topical approach appears to be promising for future epilation therapies, and may rival currently used epilation modalities, which can frequently be associated with a host of unwanted side effects.

In the experiment, 15 percent glycyrrhizic acid was dissolved in an aqueous solution containing 10 percent urea and 20 percent ethanol at 80 degrees Celsius. The solution was cooled down to 40 degrees and topically applied to the back of the neck of Wistar rats twice a day for two weeks followed by four weeks without treatment for a total of two years. Histological analysis, scanning electron microscopy as well as in situ TUNEL assay were performed evaluating treatment outcomes.
Results showed that hair loss was visible as early as three days after the first treatment application of the solution, and after six to 12 days of treatment, the targeted skin was nearly free of hairs without any sign of skin irritation or other unwanted side effects.""


I hope you'll find this info usefull.

Very interesting...Thyme & Rosemary have long been known for their purification properties among other things.I will make a note of your findings, as I have someone in mind. The Licorice
I would be cautious of as it's effect on the heart and Rosemary with care on people with high blood pressure.
Have you studied skin regeneration yet, I would be most interested; as others I'm sure would be.
Or in healing scar tissue?
Thanks!

Hi, Gypsy Girl !
We are only interested in it's effect on the skin, it's not "drinkable" ! May be I have to mention it, but I only recommend to use these natural ingreds in homemade cosmetics, not to eat or to drink.

Hypericum Oil, Tamanu oil, Hemp Seed Oil, Neem Oil have amazing regenerating properties. Unfortunately the smell of Tamanu and Neem Oils is eeee... unique (stinky), but they are extremely good regenerators... If you'd like to try it, it's better to test both of them first, because I know people who allergic to them. Hypericum Oil, Hemp Seed Oil also have very good skin-regenerating effect and they are not smelly... If you are asking about scar-healing ingreds I also can recommend Patchouly EO.

Thanks, Galia.
No...He, He, I wasn't going to put it in my mouth,
anything that goes on your skin, as you know, goes in your body. So in that respect I would use caution. I am excited about trying these things out, if the person lets me, they have old acne scars,I can't see them but they can. Thanks again!
