Are there fresh guava leaves in this supermarket?

Yes

Visit the store once

I think no.. I did not saw

Need to go and find out, im surprised to hear tbat guava leaves are edible and seems helpful for a given purpose, i have seen guava here, chances are they may have guava leaves too

They don't have a huge selection of fresh fruit, mostly dried packages items. Not sure about guava leaves specifically - maybe call the store to inquire
