When all your hand-washing and vitamin-C popping fails and you succumb to a cold, chicken soup is no longer your only way out.

When all your attempts to keep the germs away -- hand-washing and vitamin-C popping -- fail you and you succumb to a cold, chicken soup is no longer your only way out. Spas are jumping to the rescue with treatments designed to boost your immune system and get you breathing deeply again.

1. Golden Door
Carefree, Arizona
The "breathe easy" treatment helps relieve sinus congestion with a lavender-eucalyptus ointment that's massaged onto your chest, neck and face. This rub-down is followed by warm towels and then a scalp and face massage designed to clear your passageways even more.

2. The Spring
Desert Hot Springs, California
The "immune boosting buff" here starts with a full-body exfoliation and then moves on to a massage that's reported to cleanse, restore and detoxify, helped along by the rosemary oil. You might also opt for a detoxifying salt scrub with antioxidant properties – that treatment is followed up with green tea and lavender lotion.

3. Pavia Day Spa
Saratoga, California
A "eucalyptus immunity boost" massage at this Tuscan-themed spa makes use of antiviral and antibacterial oils like eucalyptus, tea tree, lemon and peppermint. After the massage, you can further sweat out those toxins with a body wrap. And you get to take home some of the immunity-boosting rub.

4. Willow Stream Spa
Scottsdale, Arizona
This desert oasis offers several healing treatments, as well as a serene setting with pools and streams. The thalaso kur and herbal kur treatments utilize seaweed, acupressure, lavender and chamomile. The desert purification includes use of cornmeal, clay and a wrap made of fiber from a local cactus plant.

5. Four Seasons
Las Vegas, Nevada
The Bali spice ritual at this luxurious, Asian-themed spa uses cloves, ginger and boreh spices (an ancient remedy for headaches and aching muscles). Warm towels follow the massage. The spa also offers a "thai herbal poultice massage," reported to release tension with medicinal-level heat.

6. Bliss Spas
New York, Chicago and More
If you can't blame what ails you on the cold and flu season but instead have to acknowledge last night's intake of alcohol, you might want to try "the hangover herbie." This gentle treatment utilizes purifying oils in a body wrap, a cleansing mask and a 15-minute foot massage.

7. Aequis Spa
Portland, Oregon
This urban retreat features a whole series of wellness treatments. You can opt for aromatherapy-based treatments using juniper, cypress and cedar to purify and detoxify or the "rajas wellness therapy," a two-hour treatment including a dead salt glow and steam therapy. If you're hard-core, try the five-day Ayurvedic purification package.
