Put the jewelweed into the pint size Mason jar. You want enough plant material so that the jar is about half full.
Cover the jewelweed completely with olive oil or coconut oil.
Fill a pot halfway with water and place a cotton cloth (like a washcloth) at the bottom. Put the jar on top of the cloth (this helps keep the jar from breaking).
Turn the heat to medium low and bring the water to a simmer. Reduce the heat if needed so that the water is very hot, but not boiling. Heat the jar in the water bath on low heat for about 3 hours.
Once the jewelweed infused oil is done, strain the mixture through a cheesecloth. Give it a good squeeze to get the most out of it.
Make the Salve
Add 1 cup of the herb infused oil and the beeswax into the top of a double boiler and gently heat until the wax is melted.
Remove from the heat and stir in the essential oils and vitamin E if using.
Pour into small tins or glass jars and allow to cool completely.
Notes
Add some plantain herb leaves into the oil too for extra skin soothing properties.
Store in a cool, dark place. This should last for about 6 months if stored properly, but toss it if it starts to look or smell off.
