Natural Aromatherapy. Caught a cold? Try hanging a bundle of eucalyptus (sold at craft stores and flower shops) from your shower curtain rod. "The heat and steam help to activate the herb's essential oils, which can ease congestion," Seo explains. Hang a bundle with natural garden twine (more moisture-resistant than cotton twine) on the shower rod, away from the spray of the water. Enjoy the scent for a few weeks as you take a hot shower.
