how to make kadha for cough and cold - #24365

I am struggling with this nagging cough and cold that just won't go away, and I remember my grandmother used to make this amazing kadha that always helped. But like, I have no idea how to make kadha for cough and cold myself! I tried looking it up online, but there are, like, a million different recipes and I can’t tell which one's the best or most effective. I kinda remember her using things like ginger, turmeric, and maybe some black pepper, but I don’t know how much I should use or if there are other ingredients I should include. Last week, I even felt so bad that I woke up in the middle of the night coughing, and all I wanted was a warm cup of that kadha, but I had no clue how to make it! Can someone please help me with a simple way on how to make kadha for cough and cold? Or like, do you have any tips on making it taste better, 'cause I'm not great with bitter flavors, lol. Seriously, any advice would be soooo appreciated!
