Question: I used to like this product and the fresh, natural scent. The consistency and scent have changed over the years. Recent purchases have been lumpy and almost impossible to squeeze out of the tube. I wonder if it is just very old and the scent and consistency have gone bad? I will not order again.

Answer:
negative
