Which statement about room spray ratios is correct?

• A. Two drops per cup
• B. Four drops per cup
• C. Six drops per cup
• D. Eight drops per cup

Answer: (B)

The idea behind room spray ratios is to achieve a balanced aroma that is noticeable but not overpowering. Four drops per cup provides a comfortable, moderate strength that most people find pleasant in a typical room. Two drops tends to be too subtle to notice, while six or eight drops can create an aroma that is strong enough to be overwhelming or irritating, especially for people with sensitivities. This baseline lets you adjust upward if you need a stronger scent, but starting with four drops per cup gives a reliable, well-rounded level.

When making a spray, pair the essential oils with a dispersing agent such as a splash of vodka or a bit of witch hazel to help the oil mix into the water, then fill with distilled water and shake before use. Also consider safety: some oils can irritate airways or be unsuitable for certain people or pets, so start light and adjust carefully.
