Guest guest Posted March 18, 2003 Report Share Posted March 18, 2003 I didn't realize that methyl was a salicylate? Well, I guess that makes sense now. Tami Re: LoriI have tried steaming my nose and from time to time, added Olbas oil, Vicks vapour rub, and tea tree oil. Since the vapour only is taken in, it seems quite safe. Is Oregano oil similar to any of these?Is there any evidence that breathing these oils could combat fungal sinus infections?. Quote Link to comment Share on other sites More sharing options...

It's 108 pages long, has over 400 references, I would say takes a very sensible, balanced view, and concludes that methyl salicylate (and hence wintergreen oil, sweet birch oil etc.) is safe to use on the skin at up to 0.6%. Before reading this review I had concluded from my own calculations that MS was safe to use at up to 0.2%. I think it's important to recognize that there is a theoretical safe exposure level for any substance (even carcinogens), even though sometimes that level is so low that it's not practical. In the case of MS there are a number of liniment type products that contain very high concentrations - 12.8%, 20%, 25% etc. Such products should not be used during pregnancy, they are very dangerous if taken concurrently with a blood-thinning drugs such as warfarin, and there is a high risk of skin irritation. By the way, it's my firm belief that the wintergreen oil coming out of Nepal is totally natural. Tisserand Quote Link to comment Share on other sites More sharing options...

For your reference here are my calculations: 12.5% methyl salicy X % max Methyl Sal. AKA wintergreen ------------------- = -------------------------------------------- blood level Cmax 6mg/L blood level Cmax 0.2 mg/L max wintergreen per base salve for 2X/ day application: 0.4% I'm still going to check these over with my pharmacist friend and see what she thinks.

I had assumed 50%, but revising that factor leads me to agree with your 0.4%, even though from a completely different calculation. Hopefully this finally answers the question. Still on wintergreen, I received a private email challenging my assertion that the oil from Nepal was natural. I contacted beth Vossen, a Belgian supplier, and I think her reply is worth sharing: Dear , It is nice to hear from you again after quite a while. I can guarantee that our wintergreen oil is indeed 100% pure and natural oil distilled from the wintergreen plant. Wintergreen grows wild in Nepal and is collected in the mountains for steam distillation. Find herewith a picture of the plant taken by myself in Lele, Nepal. Our wintergreen oil is not composed of 100% methyl salicylate but contains 97 to 99.5% depending on the lots. (but if analyzed by GC/MS the result will almost always indicate 100% m/s) Some of our customers prefer to buy " red wintergreen oil " to be sure that the are not buying synthetic methyl salicylate. We have both colourless oil (distilled in stainless steel distillation units) and red oil (the red colour comes from interaction with the metal of the distillation unit). Apparently there is no red synthetic methyl salicylate on the market ...? Anyway, there are no chemical factories in Nepal so they would not be able to manufacture synthetic methyl salicylate. What they have is good climate and lots of nature (= wild, organic plants) and know-how about distillation and ayurveda, and with the help of crazy people like us and some NGO's they have some good distillation units. But I think the most convincing argument is that our wintergreen oil is certified organic, which means that the Ecocert and SKAL/Control Union inspectors from Europe and India have visited the collection areas and distillation units and have checked all the records and accounts (quantity of raw material collected versus number of vessels distilled versus quantity of oil produced versus quantity of oil exported from Nepal versus quantity of oil imported in Belgium versus quantity of oil invoiced to customers). Of course if all this is not convincing, you are most welcome to visit the distillation units in Nepal where we distill the wintergreen. If I am not mistaken, the collection and distillation is being done all year round, except when there is too much snow in the high mountains. Lele is about 4 hours drive from Kathmandu so it's quite easy to reach. I hope this helps to convince your colleagues. Don't hesitate to ask more if needed. Best regards, beth Sounds good to me.
