Once boiling, remove 1/4 cup of the water and pour it into a jar.
Add the rosehips to the jar, cover tightly with lid, and shake well. Let it steep for at least 3 hours.
Meanwhile keep the saucepan with remaining water over very low heat and add the thyme, mullein, and sage. Simmer the herbs while stirring occasionally until liquid is reduced by half.
Remove the pan from heat and let everything steep for 8 hours.
Strain the herbs with a fine mesh strainer or cheese cloth into a jar.
Add the raw honey and shake until very well blended. It will mix easier if the liquid is still warm.
Notes
The longer the herbs steep, the better but if you only have a few hours that's fine. I recommend letting them steep all day or overnight. Stored in the fridge the syrup should keep about 1 month. Do not feed raw honey to babies! Not meant for children younger than 1. Only use raw honey and preferably local for full benefit. Recommended dosages: Children 2 and up: 5-10 ml every few hours as needed Adults: 10-20 ml every few hours as needed
