GOOT - garlic, olive oil, coconut oil. Mince 2-3 fresh cloves of garlic and let soak in 2 tablespoons of each oil and rub on throat, behind ears, soles of feet (and cover with socks), underarms, sinuses, in ears and nose. Excellent anti bacterial and will fight off cold and germs.
Essential oils - lavender, tea tree, peppermint, oregano, eucalyptus, any citrus, etc. You can look them up online to see each use and how to create different blends for different things. I use lavender for just about everything. It's anti-bacterial and calming. You can add a few drops of whatever into the goot mix too for added benefits and protection. You can also get a standard melt warmer or a humidifier and add a few drops in there too to put into the air. The ones i named are safe for pregnancy, but there are a lot of other ones too - just make sure they're good for right now.
Vitamin C - up to 2,000mg. NOW brand is great!
Zinc
Hot tea with honey - i like peppermint or red raspberry
Fruit smoothie - lots of fruit but also lots of fresh spinach or kale and carrots (carrot juice) for lots of vitamins.
Make a salad. Any fresh greens is great for fighting sickness and believe me it will help you feel better for other prego symptoms.
Veggie broth - lots of fresh garlic, onions, potatoes, some olive oil. Let simmer. Sea salt. Fresh herbs - rosemary is good anti-bacterial one.
Apple Cider Vinegar - drink a 'shot' or two straight or dress a salad. Adding a little bit of honey will make it easier going down if you're not a fan. I like Braggs brand best. It has live mother culture.
A tablespoon or two of raw honey mixed with cinnamon.
That's all I can think of right now. I started getting a cold last week.... earache and sore throat. I only had it for one miserable night. I drenched myself in oils and drank lots of tea and continually blew/coughed up all the icky stuff. I was almost over it the next day.
And having someone deep massage oils into the soles of your feet would be great. It goes directly into the bloodstream that way.
