The thing with licorice is that it should not be used alone for long periods of time - in a mix of herbs, it works well, other than potentially causing low potassium (which I address). This may be why you read that it may cause muscle and tendon issues???
(I've used licorice, combined with peppermint and white peony root as an intestinal cramp relieving formula daily for the last 7 years)
I would still encourage you to do the saliva testing, it's not vague at all. They are testing the amount of cortisol. If you are just a little low, it would still show up, as long as you do at least a 4 point saliva test. And I would encourage you to do so also because the adrenals are not something we want to mess around with. I've been trying to recover from serious adrenals issues for the last 3 years, which has really messed with trying to recover from my reinfection of Lyme and company.
That being said, Byron White formulas are generally good, although I have not researched their adrenal meds.
I do know that those with serious symptoms of these infections often find that BW formulas are pretty hard hitting - so it may be the same with the adrenal formula as well.
Maybe it's time to find a more gentle treatment path? Personally, I like NatrBio's adrenal meds, although I did have to start out on something different.
Another thing to look into would be adaptogenic herbs. I'm in love with these things! LOL! They work to normalize things, find the right balance, so there's little monitoring that needs to be done. Personally, because my adrenals were so depleted, I use ashwaganda (Gaia brand, phytocaps), but if you aren't having more serious issues with your adrenals, it could be too much as well, so I would suggest using one with the dried herb in it instead, if you choose to try ashwagandha.
If the adrenals are running a little on the high side (this is where testing really helps to understand what's going on), then Tulsi is actually the better option, as it more easily lowers cortisol, but is also an adaptogenic herb, so it will bring the adrenals back into balance.
And, as always - best of luck with this!!!
