Good recipe for lung congestion and circulation I use myself & you can substitute honey instead of syrup as I do because it's healthier but not as sweet incase you need help with the pepper use maple syrup and adding 1/2-1 oz of your favorite whiskey or brandy does make it work better but works well without for those whom do not imbibe !
1/2-1 lemon (squeeze juice in the cup and add the lemon slices quartered in as well) then add 2 tsp maple syrup or honey then hot water to about 3/4ths full in your cup and sprinkle cayenne pepper to taste and the more you can tolerate the better as I dose mine really heavy and it is still a sweet heat and very pleasant to drink ! Enjoy !!!
