I have been buying Dr. Bronner's Liquid Castile Soaps for a long time. I remember back when they were very difficult to find and the paper labels were not stuck on the containers very well. Dr. Bronner had a most fascinating life. He was ejected from his parents' home back before Hitler took over Germany and tried to take over the world. His parents were angry at him for mixing the generational soap business with politics. He was very vehemently protesting the Nazi party and warned of what was happening but his parents didn't want to hear it and were convinced it would never happen. Dr Bronner ended up in the US, where he was very vocal in protesting any dictatorship that would try to take peace from the world. One of the most poignant moments of the Dr Bronner's story was his receipt of a postcard from Germany when everything was censored and life was horrible. On that post card were the words, "You were right" His parents were murdered in the concentration camps. Dr Bronner was a master soap maker who was so affected by what happened in Germany that he spent the rest of his life trying to insure world peace. If you have ever seen a Dr Bronner's label, you will see a ton of teeny tiny writing of all kinds of statements that seem like rambling and raving. Dr Bronner put his heart and soul into producing his liquid soaps since way back in the mid 1900s after escaping from a mental institution. His random raving but heart felt passion captured the hearts of many during the hippie days in California. His soaps captured the passion for a simple purchase to use for just about any job from dishes, to laundry, to hair, and tooth brushing. There are many different scents, including a scent free version. Although the formula has changed a bit to include hemp oil (for its high essential fatty acids) , it is still pretty good and versatile. You have to remember to DILUTE it, however, or it will be too harsh. Effectiveness I always make sure to have a stock of Dr Bronner's in our household. It is fantastic to use for cleaning floors, dishes, brushes, and even laundry. I also use certain scents to battle rashes on my skin and combined with a Clarisonic, the results are amazing. The key to using Dr Bronner's, is to find the right dilution to use for the right process- don't use this full strength. On the side of the bottle which has become more simplified since the old days, you will find a chart for how to dilute the soap for each use. I have had great results using Dr Bronner's soap for many different uses, and I also have had great results using it for a flea bath on our cat. It rinses out well, does not leave skin very stripped or tight, and I even use it diluted in our hand soap bottle. Scent I have used every single scent that Dr Bronner's has come out with over the years. The Peppermint is fantastic (love how it tingles on the skin) and is probably one of our favorites. Eucalyptus is also a great scent and good for putting in steaming water and inhaling during a cold. Tea Tree and Lavender are great scents and extremely helpful in battling rashes. Almond is a different scent which is nice to use and brings a nice brisk feeling when using it, and the baby scent was also really nice too. I like to get the unscented version and make my own scents using essential oils, which work beautifully. All scents smell natural and not fake in any way. I have not seen the rose scent lately so I am thinking it might have been discontinued. That one was not overly strong, but I did like it.
