with Ann on the Epsom Salts, it's surely for people too. My arthritic hands and feet just love the hot Epsom Salts bath.
I got Tylenol up in Canada that has a muscle relaxant in it. Down here it's by Rx only but up there it's over the counter. Canada's a bit more progressive on releasing drugs from prescription requirements, they had ibuprofen over the counter years before we did. But as I said above the anti-inflammatories don't help with my back pain anyway because it's caused by muscle spasms not inflammation.
How about trying some non-toxic spray weed killers like vinegar solution? If you can kill 'em from a distance, you won't have to reach between the rose bushes for them.
