American herbalist Matthew Wood has a recipe for the infused oil.
use 7 oz. dry plant material (root) and 1 cup of safflower or olive oil--let this sit covered for 6 weeks. Alternatively you can gently heat, but not boil the same ingredients for a four hour period to infuse the oil.
For a salve mix: 3/4 cup + 5tsp. of infused oil, 1600 IU vitamin E oil, and 3 tbsp. grated beeswax. Gently heat until it melts and stir together, then you can pour into a container for use.
this recipe was from Pip Waller's "Herbal Handbook for Home and Health" book.
I would dry them if you were going to use the 6 week method, otherwise I don't see why heating them in the oil wouldnt work. I have a friend who does a cbd oil with her hemp buds and she does both dry and fresh.
I sliced the roots to dry in a dehydrator. I didnt make them very thin. I sliced them about 1/4 inch and they have shrunk to about 1/8 inch so far. I started it about 5 hours ago. I plan to let them dry overnight and will put them in coconut oil tomorrow morning.
How did your oil turn out? Would be curious to hear how it worked. I have used Solomon’s Seal internally (tincture, tea, and chewing the root) to great effect but never externally and would love to hear how it went as it is something I have considered making myself, but am hesitant, given that at least where I live, it is not a terribly common plant.
If you plan to make further oils or salves for this issue, another thing to try adding might be Cottonwood buds. I have not used them myself, but my herbalist friend and mentor suggested them for joint pain.
Perhaps you have already considered this, but tending to the muscles surrounding an achy joint can make a tremendous difference. Gentle stretching, foam rolling and massage are wonderful for this. As a massage therapist, I often find that knee pain is accompanied by tight quadriceps, hamstrings and iliotibial bands, among other things. Working on these muscle groups has often provided significant relief. Epsom salt baths can help quite a bit as well, as most folks do not get enough magnesium, which is vital to muscle health.
