I am sorry to hear your mom is experiencing such difficulty. I've read testimonials on MSM soap and lotion for reducing external skin conditions such as scars and eczema. MSM taken internally aids in fluid reduction in the lungs as well as the cells, helping to reduce inflammation throughout the body. Try nettle tea for the lungs. I noticed considerable improvement in my breathing in a few days. I drank two cups a day. Most health food stores carry it but you may find it at GNC. You can purchase all at drugstore.com. I like drugstore.com a lot -- they deliver quickly and offer discounts.
