8. Chaparral Tea

NOTE: this herb is not advised for long-term use or for people with liver disorders.
The chaparral herb relieves lung irritation and moderates histamine response, making it extremely helpful for bronchitis and colds. In addition, this plant contains an antioxidant substance called NDGA (nordihydroguaiaretic acid) that reduces the ability of abnormal (cancer) cells to generate energy.
Taken as a tea, chaparral is a natural expectorant (14).
For tea, steep 5 tablespoons of dried leaves and stems of chaparral per quart of boiling water.
9. Peppermint Steam Bath

Menthol, a compound in peppermint, is an anti-spasmodic and anti-inflammatory compound. As such, it relaxes the respiratory tract. Peppermint steam cleans mucus (and the toxins it contains) from the lungs, detoxifying your organs. In fact, it’s one of the best essential oils for colds.
To use, pour boiling water into a large glass bowl and add 3 drops of peppermint essential oil. Place a towel over your head and the steaming bowl (don’t put your face too close!). Close your eyes and inhale the vapor until the steam dissipates. Blow your nose regularly to get rid of the mucus that will flow right out. It’s great for a stubborn head cold too!
