ah, two of my most used and loved herbs!!!

elderberry can give an amazing amount of energy, Donald Yance, an herbalist and cancer specialist, considers it to be a superior adaptogen, and several studies have been done on it's effect on modulating stress (on fighter jet pilots if I recall correctly, I'll have to dig the study up again).

I use it for brain fog, immune modulation, exhaustion, stress and myriad other things.... I have taken it and prescribed it long term as a tonic to others, including children, with no problem at all. What kind of dosage are you using? The infusion is also lovely and very nutritive and tasty.

Any of the blue or black berried Elders should work just fine, most people advise to stay away from the red berries.

And don't forget about the amazing wound healing powers of the leaves, and magic of the flowers too! A truly magical plant.

The Sages are another one of my closest allies, and I have worked literally dozens of species at this point. For most uses of Sage the well-known culinary Sage, (Salvia officinale) is lovely.... If you feel called to more than one species though, by all means go for it. I have yet to meet a non-medicinal Sage. There's another long post I did on the varieties of Sage on Tribe somewhere that I'll try to find and give you the link as I think you'll find it useful.

Other Sages I'm particularly fond of medicinally are: S. greggii, S. azurea, S. subincisa, S. apiana and S. reflexa it does depend greatly on where you're living because many Sages are sunbelt type plants and prefer lots of warmth... but Garden Sage seems to do well nearly anywhere. And was there a particular way you were most interested in using Sage for? Because that could determine which Sage you might want as well.
