Cross-referencing clinical data
A pairing appears on this page only when a trial gave both ingredients together and measured the result. Sagebrush has none that clears that bar.
Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.
No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.
Research strength. Research strength says how much work stands behind the combination. It is never a product score.
Independent record. Every finding is cited to a named trial, dated, and never written by the brand.
20 pairings are live across the library today. Checked 20 July 2026.
No study gave these as a pair, so they are not in the card above. But the reason they belong together is settled biochemistry, not a guess, so it is worth knowing.
Sagebrush and wormwood share a genus and a thujone-bearing volatile oil chemistry. Taking both raises total thujone exposure from two sources that look separate on a label. Thujone intake is capped in food law across most jurisdictions for good reason, so the combined figure is what matters.
Salvia officinalis oil carries thujone alongside camphor and cineole, overlapping with sagebrush's own profile. Stacking thujone-bearing botanicals adds the exposures together. Thujone-reduced or thujone-free extracts of either plant change the picture entirely, so the extract specification is the deciding detail.
Thujone blocks the GABA-A receptor, which is the opposite direction to agents that enhance GABAergic signalling. On mechanism the two work against each other. This is receptor pharmacology characterised in laboratory preparations, not something quantified in people taking supplements.
Valerian is used for its GABAergic effects and thujone opposes signalling at that same receptor. The predicted result is that a thujone-containing preparation blunts what valerian is taken for. The direction follows from receptor pharmacology and has not been measured as a clinical interaction.
Sagebrush pollen is a major seasonal allergen and sits in the same botanical family as chamomile, ragweed and marigold. People sensitised to one Asteraceae member react to others more often than chance. Anyone with known ragweed or mugwort sensitivity should approach both with care.
The Asteraceae cross-reactivity that links sagebrush, mugwort and ragweed extends to milk thistle. The relevance is allergic sensitivity rather than any pharmacological interaction between them. It matters most for people with a known reaction to one family member.
Camphor, cineole and thujone are lipophilic monoterpenes that dissolve readily in medium chain triglycerides. A lipid carrier is the standard way to hold a volatile oil in a dose form. It is a solubility and delivery relationship, and it does nothing to lower the thujone exposure.
Monoterpenes and sesquiterpenes degrade oxidatively, forming peroxides and altered constituents that were not in the fresh oil. Tocopherol is added to volatile oil preparations to slow that degradation. This is stability chemistry, and it protects the specification rather than adding any activity.
Concentrated monoterpene oils taken orally are locally irritating to the gastric and oesophageal lining in a dose-related way. Two of them together add that load. Enteric coating changes where the exposure happens but not the total.
Nothing specific on file for Sagebrush. Match the label to the daily amount above, and tell your doctor what you take.
Not medical advice. Show the label to your pharmacist.Read this carefully. These are 155 voluntary, unverified reactions reported to the FDA (openFDA). The number mostly reflects how popular Sagebrush is, not how risky it is. A report is not proof Sagebrush caused anything. It is a signal of what to watch for, nothing more.
