What type of crock stoneware teapot or kettle is this?

Search all over no sign of it what search terms should I use. The pot is 6" tall

 

I thought there would be lots out there but I could only fine one, link below.
I could be way off base but I've always thought they are Chinese or Japanese.

Hi M,
I could be wrong, but I thought these pots were used in Traditional Chinese Medicine to boil and reduce leaves, roots and plants. As you have to boil the contents for some time (as long as an hour), the water can boil over and cause the stains you see down the sides and underneath. Your pot would have been for a lighter "tea" mixture and strained into cups. The other pot I posted below is for larger and stronger herbs and plants and is similar to the one I have at home. The smell while reducing these herbs is often overpowering, but the health benefits often incredibly successful. We have many large and successful TCM stores and dispensaries in Sydney and TCM practice is a growing alternative health field.

 

Thanks cxgirl that label on that one is interesting.
AuDragon that is also a love of mine on a much smaller scale than what you are doing. I love my teas and herb mine are mostly brought at the local grocery store
