Mucus is clear, and has been for weeks now. Completely clear.
It does not sound like there is an infection. Therefore this is most likely sinus drainage from allergies.
I can't get the powders right now.
So my main question is can I drink the strong tea made from the herbs safely?
Because it does not appear to be from an infection I recommend switching your focus to building up the adrenals instead.
If you decide to still use the herbs they would be better taken as powders in capsules. Chaparral is too resinous to really make a tea since resins and water don't mix. And the other herbs will lose effectiveness as a tea as the heat volatilizes their essential oils. The eucalyptus will already be in the form of the essential oil, so this can also be put in to a capsule without dissolving the capsule.
