4. Turmeric
Turmeric is one of the greatest possible natural immune boosters, and it’s a great idea to add turmeric to your diet as your all-in-one booster for when you want to give your body a bit of a leg-up during times where the flu of the season makes it’s way around – or when you just want to ensure that your immune system is in optimal condition.
It’s most commonly known as an ingredient that completes a healthy curry, but that’s not all that you can do with it – and you can even add some turmeric to milk and turn it into a steeped turmeric drink for a quick boost of health, with cinnamon and lemon juice optional.
Turmeric is great for restoring your immune system if you suffer from ischemic colitis, and it even has plenty of digestive benefits. Just be careful to not dye absolutely everything that it touches yellow.
