Thank you very much, very helpful and informative. I have a lot of rosemary growing in my garden and am now looking forward to trying out all the methods described in your video. Xx
Dr. Leo Kwok....great job explaining the products and process along with health benefits. Thank you for sharing your knowledge. I have two large Rosemary plants at home and now know exactly what to do with them.
Can we leave the bottle with oil with dried rosemary under direct sunlight for the infusion method for a few weeks. The only concern is if the sunlight will oxidize the oil. But I’m only looking for external application on the skin and scalp. Not for consumption. Please advise. Thank you
It is good to use dry rosemary with oil but avoid sunlight. The UV light in sunlight can deteriorate oil. You can put the bottle in cabinet in kitchen. The little bit warm can help your extraction.
Thank you so much for explaining about the Rosemary I know about the three different ways but I didn't know about the the last when you talked about thank you very much and God bless you and your family
Thank you! I am glad you like this video. About distillation you may watch another video making essential oil and hydrosol at home : ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-V5E9f0anaEg.html
It is not necessary to dry rosemary before extraction. However, for infusion and tincture cellular water will comes out from fresh rosemary during soaking which can dilute your extract. For rosemary, there is over 60% of water mass in the fresh herb. Drying can help reduce dilution. Again, drying is not necessary but it can help you get more concentrated product.
I just set up my homemade distiller. I was using lemon peels. I barely got any oil out of them. I used about 12 lemons and chopped up the lemon peels. I put about 1/3 full of water in a 6 L pot. I set temperature about medium high. Cooled water as it went through copper tubing. I got lots of liquid but only a light few drops of oil. Was I to steam them on a lower heat? What could I do to extract oil better next time? Or do I need more lemons?
👋 Hello is it possible to do Rosemary Ice extraction. I've recently learned about this method and was curious about your thoughts. I will be trying it out on my own.
@Dr. Kwok, the infused oil requires 4-8 weeks of time to infuse, *but,* if you use a double boiler, how many weeks do you have to wait? Your explanation forgot that information. .....Also, *if you use a double boiler, how much cooking time should we use??* Thank you, sir.
Hi, with double boiler the time can be saved into 1-2 weeks. Normally the slow cooking will take hours. Longer slow cooking time can save your soaking time after. Or the oil can used right after. Difference is slow cooking can help extract most of essential compounds out and the rest will be extracted during regular soaking. Hope this help answer your questions. Please send me email for any further questions: leo@letimestill.com
Yes, dried rosemary works perfectly for making tincture and infused oil. They are more potent and have less chance go bad than fresh ones due to its less moisture content.
Herb essential compounds have fairly thermal stability and can tolerate heat. Boiling water or steam won’t cause damage to mostly compounds. Boiled Oil has higher temperature which could have some irreversible effects on some compounds but more compounds have higher solubility in oil than water. If oil is going to be used, either use it at room temperature or heated up at low heat without boiling. Hope this answer can help you. If you have further questions please email me.
Pure olive oil with dry rosemary can have a good shelf life without saving in refrigerator. If fresh rosemary was used, moisture in the plant could go into oil and that could cause problem during storage.
Hello doctor🩷How long how many minutes can I heat up in the double boiler the rosemary leaves in olive oil to make a rosemary oil? Please help🙏🏼🙏🏼🙏🏼 Thank you in advance😊🙏🏼
We have another video talking about making rosemary dipping oil. Make Rosemary Dipping Oil. Tasty Rosemary Oil. How to Make Rosemary Infused Oil. Rosemary Oil ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-icYqLKGWAWo.html
Hi! l didn't get the first way exactly. In the first way that is infusion heating is necessity or not? What that I,ve got is that we should soak the rosemary needles into olive oil and put it away for 8 weeks. After 8 weeks we can use it. But if we want to use it immediately we have to haet it. Am I right?
Hi, room temperature is the common way for making infused oil. Heat up can help shorten time but don’t go beyond 140F. Otherwise you will lose their essential compounds. By heating up for example in a slow cooker at low heat, you may use it after 24 hours or longer longer time.
They do but with different amount of oil being extracted. Tea has the least because of its low solubility of oil and low temperature. Oil and alcohol has more oil being dissolved in them. I am having a new video coming out this Saturday, Jun 19th, explaining ways to extract oil and their history. Stay tuned!
