I’ve found this to be more effective than commercial cough rubs.
7 T coconut oil
1 T olive oil
10 drops tea tree (melaleuca) essential oil
10 drops rosemary essential oil
10 drops eucalyptus essential oil
In a small pan, melt the coconut oil and olive oil.
Stir until melted.
Add the essential oils and stir to combine.
Rub on chest to relieve cough.
