I read that redistillation can really improve the purity of essential oils.

That sounds interesting! How does it work exactly?

Basically, it involves distilling the liquid multiple times to remove impurities.

Wow, I had no idea it was that effective. I might try it for my homemade blends!

Root Explanation
Redistillation → It is formed from "re-" (meaning again) and "distillare" (meaning to drip or distill). The word refers to the process of distilling a substance again, often to purify it further.
Memory Tip
Think of the process of distilling something 'again' ('re-') to make it purer, which is what redistillation means.
