canker sores stops any kind of pain within seconds. Heals up very quickly. The lid was glued on and I had to pry it loose from the glue(its not my grip). Other than the stupid glue keeping the lid from being unscrewed it's perfect. It works so well I am surprised it's still legal.

It really works! I cut off about an inch of the stem, dipped the hydrangea into the Alum and added it to a vase full of flowers. It lasted for two weeks. No more shriveled up hydrangeas for me.

I use this for flower arrangements for Parties on my fresh cut hydrangeas. Before I knew this secret my hydrangeas would wilt within hours or a day. Cutting them with a blade at an angle and dipping the cut stem in this preserves them and they last for weeks!
