These four tools answer the questions a page of text cannot answer for you. The essential-oil dilution calculator turns a percentage into drops and milliliters for any bottle size, with guidance by age group. The blend builder lets you pick oils, checks the balance of top, middle and base notes, flags safety conflicts and gives you a drop count. The oil safety lookup filters every oil we cover by its cautions for dogs, cats, pregnancy, young children and sun sensitivity. The nutrient RDA lookup shows the recommended amount and the upper limit for your age, sex and life stage, using the NIH Office of Dietary Supplements tables. Each tool reads from the same data as our reference pages, so the numbers always match.
