can we use this method for hibiscus leaf extraction for antibacterial activity in well diffusion method ? please tell me the easiest way for preparing plant leaf extraction.
You could use this method for leaf extraction - they should be dried and crushed first for best extraction. You would then need to check the antibacterial efficacy of your particular extract using the source and method you have used.
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?
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: info@personalcarescience.com.au they're free and available for you.
Hello to make cold pressed ashwagandha or licorice extract can l use 70 g of glycerin ,30 g of water and 10 of the root powder in a glass jar for 4 weeks away from sunlight and then strain? Is this the right way with glycerin ext ? If made in this way,will the extract be effective for cosmetic formulation? ...... kindly reply
Very interesting! Can we also apply same method with concentrated powdered extracts instead of the herb powder? And do we then need to resolve the powder in same way or can it be done without boiling?

how to make a colorless herbal decoction ? i mean how could i remove pigments of a herbal decoction so i could make a transparent liquid facial toner out of a pigmented herbal decoction (with potassium sorbate & sodium benzoate for preservation).
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
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.
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.
hi, my question is to 1. Why did you boil the herb before adding glycerin? 2. What if the plant is heat sensitive, does it mean we can't use the glycerin method?
Hi Chancey I heated the herb to extract components from it faster. This method also pasteurises the water portion because the addition of glycerin enables rapid cooling (its not pasteurisation if it is not cooled rapidly after heating). If you want to make a cold extract, you'd have to use ethanol because herbs are fantastic micro-organism growth sources if not treated effectively.
It wasn't clear what you were pouring in to dilute it and how much. Were you pouring in a 60% alcohol or were you pouring in a 100% alcohol with water on top of it to make it 60%?

What are some specific plants that are suited for oil maceration? I understand that this will only extract the oil soluble active components of the plant as you mentioned already in a comment below. I'd love to know which ones are worth doing with oil.
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! That's the fun part of R&D - exploring and working with different materials to create unique and innovative substances - just check their history of safety carefully when exploring newer materials.

This is by far the most helpful video I've come across showcasing the methods of making herbal extracts. So well explained and helpful! Thank you for sharing this! I was considering making a soothing mist using herbal extracts (of green tea, Chamomile, and sorts), for non commercial purposes. Do you think simply brewing the herbs and adding a preservative (like phenoxyethanol) along with EDTA and / or Citric Acid (for adjusting pH) to the herbal "tea" will suffice? Or will that lead to an unstable formulation and I'm required to make an extract with either of the methods as mentioned in the video, before using them in my formulation? A response would be much appreciated! Thank you in advance!
Thank you for watching! You should not use the herbal extracts in this concentrated form - they should be diluted and used in a finished product around 5%w/w. Please watch our FREE Masterclass series: personalcarescience.com.au/Workshops/CosmeticFormulationFundamentalsMasterclass-7441/ by lesson 3 you will learn how to make a mist product, and can then use your herbal extracts in this mist formula. Happy formulating!
@@theinstituteofpersonalcare6401 Thank you for responding! Apologies for not getting across clearly, by brewing I meant making a way less concentrated herbal extract/tea, say, 0.5-1 tsp of herbal powder (calendula, for example) in 100 ml water, and adding a preservative to it (say, phenoxyethanol) , thereby using it on its own. Edit : Having said that, this is a great channel and deserves a lot more attention. Been binge watching it lately! Glad to have found it. Kudos to you / the team!
when she says make up with 20% water, does she mean 20% of what you have of extract or 20% of how much you trying to make in total after adding the glycerol. TIA

hi - and thank you for your professional posts ! i would like to know how i can add alcoholic extract (tinctures) to face creams/lotions without 'making things worse' : i cannot think of a cold method that would help evaporate the alcohol,and the boiling dsnt help much with preserving the active ingredients in those extracts; is alcohol harmless to the skin and if yes - what % should i use (max) ?

This would take time to review and advise on properly, please purchase consulting time here: personalcarescience.com.au/Advice/Advice-2046/ so we can advise you properly on your specific situation. :)
Alcohol causes small fissures in the face. Much use over time, these fissures become worse, drying out the face, opening up places for infection, eating at the nerves. I don't recommend alcohol for skin care, and many of us prefer the glycerine extracts for that reason.
Heat sensitive compounds will be affected, yes, so you can use the cold ethanol extraction method to protect heat sensitive compounds. Please email us for full formulation, method and supplier details: info@personalcarescience.com.au we provide this free. Happy formulating!

If you want to extract the oil, you would need to cold press it (like vegetable oils) or other pressing method or use steam distillation. The method used for extraction shown in this video is the method that has been used for thousands of years - the filtration materials we use now are far better than they had in the old days! Don’t use regular filter paper (eg coffee filters) - that will cause issues. Use proper science brought filters so that the filter material doesn’t come out with the solute.
Hello IPCS ,, THANKS for this video.Please I have a question ..I saw brands like body deli using Acai Berry Puree, *Pomegranate Juice, *Black Cherry Juice..in their formulations .. while these are their formulas.. but still could you say how we can incorporate juices in creams DOESN'T THEY GET SPOILED ..Or we make juices like you showed here by adding glycerin to them. THANKS
You can add juices to formulas - you just need to check their quality first (need to pass cosmetic micro-organism limits for raw materials) and make sure the product is preserved well. I did something similar with herbal tea: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wkOPQLGD82U.html Its all about micro count on materials going in, packaging and preservation.

Hello Mam, Is there any way to mix these extracts in oil as you've made the extracts in either ethanol or water which both are oil repellent. How can I mix these extracts with oil.??
You could prepare that like the glycerin product - but you'll only extract the oil soluble components that way - and make sure you use suitable antioxidant for the oil you use for extraction after you've finished the extraction process. Hope this helps.
Excellent as always Belinda....I would like to ask you three questions...if I want to make fruit extracts should I use all the fruit? Is it better fresh or dry?....and if I have a publication that prove the properties of the extract and I follow their extracting method can I make the claim done in the publication ?
Hi Elisa, you could use the whole fruit or just the peel or just the inside. You could use it fresh or dry too - just make sure you follow the same procedure each time to get the same extract each time. If you follow the extraction method from a publication, you would need to send your extract for what we call an 'assay' to prove it has the same active constituent profile to validate your method - and if that assay came back with the same results then you could use the publication results - but be very careful to make sure that your assay matches exactly to prove you have created the same extract with the same content of active constituents, otherwise you can't use that evidence. Hope this helps!
You need to check the toxicity of the plant/herb you intend to use! The method (ethanol or glycerin) is perfectly safe but the herb may not be! This is for topical use only, for cosmetic application. Please check your source also for impurities.
No you can't - herbs are a fantastic source of micro-organisms unless you preserve them, or make them self preserving as I have shown. The risk to product quality and human health is not worth it, please use the methods I have shown, please email for full details: info@personalcarescience.com.au
No, you should be using pure materials, not a product. You can use isopropyl alcohol but rubbing alcohol is an already made/diluted product and is not suitable.
This extraction method will extract constituents from the plant - but not specifically concentrate them.

Hello just found your network an I'm very happy I did .Cosmologist here been doing skincare a long time .Always learning .The way I make my extracts is i put the herbs in a small crock pot add water cover .sorta the same way but i dont have to worry the stove is on or the burner ..easy pezzy Thank you I'm hoping to learn a lot!
I'm a bit confused...in both of these how-to explanations you describe the process but not the ratio of completed extract to final product? If I use 10g of plant and 20g of alcohol initially, then drain off the extract (the amount of which will vary by herb absorption), how much will that make? I get that we're adding water and more alcohol in certain percentages, but of what total? 10 times the plant materials initial weight? If I used 10 g of plant, would I end up with 100 g of final product? Or do I measure the final extract weight and consider that 10%? Or is it 5% or what? I didn't catch what ratio we're adding to either product 🤷🏻♀️

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.
@JohnA-bear idk. That's how cocaine was discovered. And laudanum, old alchemical texts give a lot of the basis of things that became integrated into modern sciences. But the discovery and extraction of cocaine and psilocybin are really good examples of this. I ferment things because I find it to be the best way in personal experience.... but in my mind, I'm just doing what Albert Hoffman did with Maria Sabina... and with ergot. Albeit with different organisms. Fermentation leads to diethylamine and other things like acytelaldehyde.. which, on their own in trace ammounts in beer, aren't very noticeable, but when combined with alkaloids found in, say, ephedra... it creates chemical analouges of ephedrine which are much better than just pure ephedrine. LSD: My Problem Child, by Albert Hoffman will give you a general idea of organic chemistry. There isn't as much lab work involved. It's a lot of brainstorming, really.
@@eastindiaV Oh wow😲 New info for me. I love it! I know about morning glory seeds, they grow wild next door to my sister's after the old lady died. Cocaine my demond, I'm staying far away. Laudanum anything to do with opioids, my stomach is in knots just thinking about it. This past summer I learned that Cuban-Jute, Sida rhombifolia which grows all over where I live contains ephedra. I'm not looking to extract that, I just find it interesting how plants containing all that stuff grows all around. I only made a handful of tinctures, the first being wild lettuce. It worked fine without getting me nauseated like I get from opioids. But it worked great on my dry cough. I missed out on this year. I'm diabetic so I made a tincture for kidney health and I believe it helped. Can't say for sure because I also changed my eating habits. I'm about to make another one using the percolation process. I guess it's a step up from the maceration process with a better yield. But I'm still interested in what you are talking about, aerobically with yeast. Is there a basic process?

So, when extracting via these methods, you include these items in the ingredients list, but you cannot include them in any marketing copy as a part of your marketing story? For example, if I do a rosemary extract in a hair growth formula, I cannot directly name the rosemary because I wouldn't have tested my homemade extract to know the true efficacy of it?

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)?
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.
@@CatarinaMota This isn't really accurate. As an herbalist, we determine this regularly without watering down the final extract. It defeats the purpose of using the initial menstruum, which is specifically mixed to a ratio necessary to pull the appropriate constituents out of the plant materials. We measure everything before we make the extracts and then measure everything after, and therefore are absolutely able to make a determination about percentages. If you're using 190 proof without any added water and doing a 1:2 ratio, you wouldn't need to add ANY water at the end. You only need for a final ratio to be 25% in order for it to be truly shelf stable. Most tinctures you buy commercially are about 40 to 60 percent because they're made using fresh plant material or a lower alcohol content to begin with. That said, this final product will be much, much higher than that since your starting herb (green tea in this case) was fully dried. There's no water to pull from the plant and none added, so it's nearly still 190. Further, you need to put all of that green tea in the filter and press it out to get all the constituents and goodness from that extract. We press our marcs to get every last drop of that liquid gold out!
When extracts are bought from a supplier, the effective pH is given. When making extracts at home, how would you tell what pH the active ingredients need to be adjusted to to be effective? Thanks!

After ethanol extraction why dilute it with water? Why not leave extract as is and for the usage simply dilute it in the cup of water right before taking the extract?
Can we omit the water in the ethanol extract? Water would activate some of the enzymes in the plant that I want to use and create a compound that is very unstable
