Review (5/5): Good product.
This one (made in Germany) you can use external and INTERNAL. Put 3-5 drops in very hot water and stir it. Wait until you can drink it - it helps a lot with a cold or breathing problems. You can apply it to your skin for muscle pain.
- Don't put in eyes - it will open them wide, wash it out - nothing bad will happen if you are careful.
Most US products of that type can't be used internally!
Our family uses it for more than 50 years very successful. Good luck.
