[@eastindiaV]

I think the best way is to take whatever you wanna extract and then ferment it aerobically with yeast. Yeast breaks down the plants more than boiling, releasing more medicinal compounds into solution via osmosis, until eventually, the liquid saturating the fermented plant material is equal to the saturation of the surrounding liquid. It also prevents heat loss of medicinal compounds and oxidization. Then, once the liquid is fermented completely, it can be further refined via fractional distillation, or by extracting with solvents. And these extracts can be studied and developed into medicines. Is how you practice medicine.

Hello indeed a very informative video! So in both of these processes we have converted powder extracts to liquid forms, is that right? Also how much time will the glycerin extract be preserved? And is it okay if we boil it for less time, like 10-15 mins or will it affect the extract's quality? Thank you.

[@theinstituteofpersonalcare6401]

Thank you for watching! You could boil it for less, it would be handy to run some efficacy tests after you have created them using different methods to make sure you get the best results. The glycerin will protect these extracts for years - 5 or more - if you follow these procedures and inputs.

Thank you for posting this video. I have no interest in turning this into a business but I do grow more herbs than I need for my own needs and I thought it might be nice to make gifts up for friends and family and some of my herbs smell quite nice but not if they are not preserved. I was going to make potpourri as well but that won't last as long as an extract and not all my herbs do well as potpourri. This is going to be a nice addition to what I am already doing.

Any plants that yield essentail oils will respond to maceration well - but you can try other herbs as well - arnica, chamomile, calendula - but there are loads of other materials that you could create that would be more unique!

Hi Belinda, thanks for sharing your knowledge. Can be used 99.9% pure isopropyl alcohol Instead of ethanol? I read that it can be use in cosmetic too. Thank you

[@theinstituteofpersonalcare6401]

Not to make extracts, no, because it may not be compatible with all formulas you create - especially where salt is present. I would recommend you stick to ethanol as it does not then interact with some materials unfavourably.

[@CatarinaMota]

Thank you so much for sharing this. I've been reading about extracts and this is one of the best tutorials I've come across. But I'm a bit confused about the percentages. If I'm not mistaken your ethanol extract was 10% concentrate, 50% added ethanol, and 40% water. Is that correct? Was the glycerin extract also based on a 10% concentrate (10% concentrate, 10% added water, 80% glycerin)?

[@theinstituteofpersonalcare6401]

No - the thing is that when you mix the herb with the ethanol or water, you don't get a 'known' amount of ethanol or water back - so you can't determine how much of the starting ethanol or water is still present at the end. You can determine the extract amount, which is what you obtain - this differs for each type of herbal extract you make, so you can't write these % as 'general' or 'standard'. You will need to add different proportions of ethanol or water after filtering each time, even with the same herb (although you will see certain herbs soak more of the starting substance than others). So you need to filter out then make up to the amount listed in the formula sheet. You can, batch by batch (herb by herb) record this to be accurate for ingredient listing, but its not something I can provide as a general standard for you - it totally depends on how much liquid you get back from that initial filtration step. It is a case by case basis depending on the herbs you use and will also have some batch to batch variation, not the generalisations. I hope this makes sense, record it carefully and you would be able to calculate it correctly for each batch at the end, but it is never a generalisation.

20% water and 80% glycerin? so it makes a 100 gm extract of 10-gram herb? am i correct? and can we add that in the same percentage of glycerin to the products to get the benefit of an extract in the creams or lotions?

[@theinstituteofpersonalcare6401]

Hi Monika, no this is not correct - please contact me for the details of how the extract was made in writing, because it is 20% extract at the end made up with water. Different extracts will yield different volumes that then need to be made up to 20%. No, adding straight glycerin won't give you the same benefits as the extract - and definitely not the 'marketing' benefits. Please email us for full details: [e-mail] they're free and available for you.
