Sniffly, red-eyed and headachy? It might not be a cold.

If the holidays are making your head ache, stress might not be the culprit. Have you checked the ingredients in that "merry-scented" candle or "fir fresh" soap?

Turns out 'tis the season for artificial fragrances and synthetic scents, and lots of us are sensitive to them. That's why we jumped at the chance to blend natural aromas at Pasadena's LATHER. Founder Emilie Davidson Hoyt is a former migraine sufferer who found relief in essential oils--and her line of creams and sprays is a breath of fresh air. We asked: What are some easy blends we can try?

• If PMS is harshing your mellow, try this.
• Bummed out? Try this.
• Trouble getting out of bed? Try this.

Take a whiff of sweet relief.
