Will gardening with bare hands block guaifenesin?
Yes. Plants in your garden produce salicylates to ward off fungus. You should wear gloves that create a barrier between your skin and plant juices. Make sure that your gloves are waterproof–leather or latex (rubber) are best. If you wear cotton gloves be sure to use a barrier cream such as Gloves in a Bottle (www.glovesinabottle.com) to protect your skin from absorbing salicylates.
