The trouble with those store-bought fragrance sticks is right in the name: fragrance. The term “fragrance” is completely unregulated, and it can refer to a slough of different chemicals. Some of these chemicals are harmless, but others are harsh toxins and even carcinogens. Suddenly, those fragrances smell a lot less sweet.

Luckily, it’s super simple to whip up fragrance sticks at home with natural scents and recycled materials. Check it!
