Lotus root is fantastic for clearing out congestion and mucus but can be a little difficult to find. What about Thyme? Thyme is a popular herb and medicinal too. It can relieve a cough, and indigestion and even fights candida. It is also touted to soothe the mind. I found this Thyme Cough syrup that says one teaspoon taken every hour will relieve a cough.
Bring one cup of water to a boil and then turn off the heat. Add 1 ½ Tablespoons of Thyme, put a lid on the pot and let it sit until cool. Strain out the Thyme and add ½ Cup of Honey or Brown rice syrup. Keep it in a glass jar in the refridgerator. It will last for several months.
