A note from Evey

A-SF is a twelve-plant blend that Byron White built around astragalus and elderberry, two of the most well-studied immune-supportive botanicals in modern herbalism, layered with bitter melon, honeysuckle, sweet wormwood, stillingia, isatis, neem, elecampane, cinnamon, echinacea, and sage. The formula's range of action sits across the upper-airway and lymphatic terrain, which is why it tends to read as more interventional than the everyday tinctures.

Most immune tinctures stop at three or four botanicals. This one runs to twelve, and the breadth is the point. A clinician can layer A-SF alongside other Byron White formulas in a guided plan, with the tincture format making it straightforward to dose-adjust as the clinical picture shifts week by week.

A-SF fits naturally alongside steady stress regulation and clinician guidance. The lymphatic system moves with breath and gentle motion, and a formula at this depth works best when there is a clinician reading the body's response alongside you.

Begin at a small drop count, observe how the body settles over time, and adjust pace with your practitioner. Steady, cumulative response over weeks is the pattern I look for and the pattern most patients describe.
