Was actually talking about citronella today and needing to find a essential oil extractor that provides good quality citronella oil.
Very important for keeping mosquito at Bay for my elders. Especially the chemically sensitive ones that can't use the big repellants and have a sensitivity to DEET. Which isn't good stuff. Similar to DDT actually.
And wish there was more books. Imagine all the books that have been lost during history...
That is correct. The oil is also good for the skin, I've even taken it out without an oil extractor. You can squeeze its leaves and mix them with hot water, put it on after you shower and it works.
