Question: is spearmint the same as peppermint?
Answer: And though peppermint is perhaps the better known of the two, it's actually a natural hybrid of spearmint and water mint. This explains why it is so much more potent than its counterpart. Because peppermint is a mix of two types of mint, it contains a higher content of menthol (40% as opposed to spearmint's 0.5%).
