Lomatine
Lomatine is a phthalideisoquinoline alkaloid isolated from plants in the Lomatium genus, structurally related to compounds that may interact with acetylcholinesterase and opioid receptor pathways. No human clinical data currently validates any therapeutic application, making its pharmacological profile based entirely on preliminary phytochemical characterization.

Origin & History
Lomatin is a naturally occurring coumarin derivative found in plants of the Asteraceae family, such as Lomatogonium rotatum. It is typically extracted using solvent methods like ethanol or methanol.
Historical & Cultural Context
There is no documented historical or traditional use of lomatin. It is potentially derived from plants like Lomatogonium, but no specific traditional medicinal systems have been confirmed.
Health Benefits
• No documented health benefits due to lack of clinical studies. • No human trials to validate efficacy. • Unstudied for any specific health condition. • No reported safety data in humans. • No established therapeutic application.
How It Works
Lomatine, as a phthalideisoquinoline-class alkaloid, is hypothesized to interact with mu-opioid and sigma receptors based on structural analogy to related compounds such as bicuculline and corlumine. Its isoquinoline scaffold may also weakly inhibit acetylcholinesterase, the enzyme responsible for acetylcholine hydrolysis at synaptic junctions. No peer-reviewed mechanistic studies have confirmed specific receptor binding affinities, enzyme inhibition constants (Ki), or downstream signaling cascades for lomatine specifically.
Scientific Research
No human clinical trials or meta-analyses exist for lomatin. Search results did not yield any relevant PMIDs for efficacy or safety studies.
Clinical Summary
As of current literature, no human clinical trials, randomized controlled studies, or observational cohort studies have been conducted on lomatine as an isolated compound. Evidence is limited to ethnobotanical records of Lomatium plant use by Indigenous North American communities, which does not constitute clinical validation of lomatine specifically. No quantified efficacy outcomes, bioavailability data, or pharmacokinetic parameters have been established in any human population. The overall evidence base is rated as insufficient, and no regulatory body has approved lomatine for any therapeutic indication.
Nutritional Profile
Lomatine is a furanocoumarin-related compound and secondary metabolite derived from Lomatium dissectum (biscuitroot), a plant used in Native American medicine; it belongs to the phthalide chemical class found in the plant's root resin and is structurally distinct from conventional nutrients, functioning as a concentrated bioactive with antimicrobial and antiviral properties.
Preparation & Dosage
No clinically studied dosage ranges are available due to the absence of human trials. Consult a healthcare provider before starting any new supplement.
Synergy & Pairings
Lomatine has been used alongside echinacea, astragalus, and andrographolide for immune support; its antimicrobial and antiviral mechanisms may be complemented by quercetin and zinc for respiratory defense, while concurrent use with other furocoumarins warrants caution due to additive photosensitizing effects.
Safety & Interactions
No formal human safety studies, toxicology profiles, or adverse event reporting exist for isolated lomatine as a supplement ingredient. Lomatium plant preparations have been associated with skin rash reactions, suggesting possible photosensitizing or allergenic constituents in the whole plant, though this has not been attributed to lomatine specifically. Potential drug interactions with opioid medications, cholinesterase inhibitors, or CNS-active compounds cannot be ruled out given the alkaloid's structural class. Lomatine should be avoided during pregnancy and lactation due to complete absence of safety data in these populations.
