Which one do you prefer for a natural cough remedy? Luya o Calamansi?

Sometimes when my throat is too sore already from phlegm and coughing, I find the calamansi too sweet and syrupy down the throat. So I'd opt for ginger instead. I like the spiciness, it's soothing down the throat. They say you can chew a little piece like a lozenge, but I think that would taste too strong. I prefer to drink it as salabat tea.
