I just tried this today after testing positive for COVID yesterday. It is my 2nd time having the virus which I got before in early 2021. Today I still had fatigue with congestion and a strong headache this morning (I never get headaches). I saw this IC and thought why not, so I made a batch in about 8oz. of water. To my surprise within 30-45 minutes of drinking it my headache went away. I felt significantly better to the point where I almost didn't feel sick anymore and got a burst of energy. I'm still resting today but I'm truly shocked at how effective this was in helping me feel better compared to the last few days. I started feeling unwell on Monday and immediately started taking more Vitamin C, Oregano Oil - 4 drops 4 times per day, Quercetin at 1000mg, Copper at 2mg as well as my usual fish oil and Vitamin D at 5000IU and drinking 2 cups of coffee with 1 cup of Matcha green tea during the day. I was truly skeptical about it but this IC has absolutely floored me to be honest. Shaking my head with 2 thumbs up!
