Galphimia Glauca 12X HPUS
Also known as: Thryallis, Mexican shrub, Galphimia, Galphimia glauca 12X HPUS, Galphimia glauca
Overview
Galphimia glauca is a tropical/subtropical shrub native to Mexico and Central America, traditionally used for its sedative, anti-inflammatory, and anti-allergic properties. The supplement form '12X HPUS' refers to a homeopathic dilution (12X) recognized by the Homeopathic Pharmacopoeia of the United States (HPUS). It is primarily used in homeopathy for hay fever (allergic rhinitis), anxiety, and asthma symptoms. The plant’s pharmacological activity is attributed mainly to galphimines, a group of triterpenoids, which interact with multiple protein targets involved in inflammation, immune response, and nervous system regulation. While traditional use and some pharmacological studies exist, high-quality clinical evidence for its efficacy, especially in highly diluted homeopathic forms, is limited. Systematic reviews and meta-analyses on homeopathic Galphimia glauca for hay fever exist but are few and have methodological limitations.
Benefits
Evidence from a meta-analysis of randomized controlled trials (RCTs) suggests that Galphimia glauca may reduce symptoms of seasonal allergic rhinitis (hay fever) compared to placebo. This meta-analysis indicated statistically significant symptom improvement (p < 0.05), with effect sizes potentially comparable to conventional antihistamines, though the included trials varied in quality and sample size. Sedative and anxiolytic effects have been reported in traditional use and preclinical studies, likely due to modulation of central nervous system targets, but robust clinical data are lacking. The primary population studied for benefits is adults with seasonal allergic rhinitis. While a moderate effect size for hay fever symptom relief is indicated, caution is advised due to wide confidence intervals and heterogeneity among studies. Symptom improvement is typically assessed over weeks of treatment in RCTs.
How it works
The active compounds in Galphimia glauca, known as galphimines, are believed to interact with over 180 identified human protein targets. These targets include key signaling proteins such as SRC, MTOR, and MAPK3, which are involved in regulating cell growth, immune response, and inflammation. The galphimines appear to exert anti-inflammatory and immunomodulatory effects, potentially blocking histamine-mediated allergic reactions. Sedative effects may involve the modulation of central nervous system pathways. However, the bioavailability and pharmacokinetics of galphimines in humans are not well characterized, and the mechanism of action for highly diluted homeopathic preparations like 12X HPUS is a subject of scientific debate.
Side effects
Galphimia glauca is generally considered possibly safe for short-term oral use in adults. Common side effects reported include tiredness, nausea, and headache, each occurring in more than 5% of users. No serious adverse effects or drug interactions have been well documented in available research. Safety in pregnancy and breastfeeding is not established, and therefore, its use is not recommended in these populations. There are no known contraindications beyond standard cautions for herbal supplements. Users should consult a healthcare professional before starting any new supplement, especially if they have pre-existing medical conditions or are taking other medications.
Dosage
The '12X HPUS' designation indicates a homeopathic dilution of 1 part in 10^12, which is a very high dilution typical in homeopathy. Clinical trials for hay fever have utilized various dosing regimens, but no standardized dosing guidelines exist for Galphimia glauca 12X HPUS. The optimal dose and duration of treatment remain unclear due to limited clinical data and the nature of homeopathic preparations. Timing of administration is typically aligned with the onset of allergy season or when symptoms appear. There are no specific absorption cofactors or form-specific recommendations established. Due to the high dilution, the pharmacological activity of such preparations is controversial, and traditional dosage concepts may not directly apply.
FAQs
Is Galphimia glauca effective for allergies?
Some evidence from meta-analyses suggests it may reduce hay fever symptoms, but the quality of evidence is moderate, and results can vary between studies.
Is Galphimia glauca safe to use?
It is generally considered possibly safe for short-term use in adults, with mild side effects like tiredness and nausea. It is not recommended during pregnancy or breastfeeding.
How quickly does Galphimia glauca work?
Symptom improvement in clinical trials has typically been observed over several weeks of consistent treatment rather than immediately.
Is the homeopathic 12X dilution pharmacologically active?
The pharmacological activity of such high dilutions is a subject of scientific debate. Any observed clinical effects may be due to placebo or other factors.

It classifies it as 'possibly safe' for short-term oral use.
- https://pubmed.ncbi.nlm.nih.gov/9381725/ – This meta-analysis of randomized controlled trials investigated homeopathic Galphimia glauca for pollinosis (seasonal allergic rhinitis). It reported statistically significant superiority over placebo in symptom relief, with effect sizes potentially comparable to conventional antihistamines, but noted limitations such as heterogeneity among studies and potential bias.
- https://www.health.gov.au/sites/default/files/2025-03/homeopathy_tr-apxabc_final.pdf – This systematic review and critique highlighted methodological issues in existing RCTs and meta-analyses concerning homeopathic treatments, including those for Galphimia glauca. It pointed out small sample sizes, inconsistent outcome measures, and potential publication bias, concluding that the evidence is insufficient to definitively recommend homeopathic Galphimia glauca for clinical use.
