The Short Answer
Tepozán leaf (Buddleja cordata) contains verbascoside at approximately 10% of methanolic extract weight, along with linarin, which provide potent antioxidant and anti-inflammatory effects. These compounds work through NF-κB pathway suppression and enzyme inhibition including cyclooxygenase and xanthine oxidase.

Health Benefits
Supports respiratory health by alleviating symptoms of bronchitis, asthma, and cough through airway opening and inflammation reduction.
Provides potent antioxidant activity, neutralizing free radicals and protecting cells from oxidative damage with flavonoids and phenolic compounds.
Aids digestion by calming the gastrointestinal tract, relieving bloating and discomfort.
Reduces systemic inflammation and pain associated with joints, muscles, and chronic conditions.
Strengthens immune response, enhancing resistance to various infections
Origin & History
Buddleja cordata (Tepozán Leaf) is a hardy shrub native to the highland regions of Mexico, thriving in cool, mountainous climates, especially in temperate forests and valleys with well-drained soils. Revered in traditional Mexican medicine for generations, it serves as a versatile botanical remedy for respiratory and inflammatory conditions, offering significant functional benefits.
“Tepozán has deep roots in Indigenous Mexican herbalism, long used for its healing properties in rural areas. The leaves symbolize resilience and holistic wellness, and the plant’s flowers play a role in traditional festivities and rituals. Today, it remains a vital part of Mexico’s phytotherapeutic heritage.”Traditional Medicine
Scientific Research
Preliminary phytochemical analyses and ethnobotanical studies support Tepozán's traditional uses, affirming its antioxidant, anti-inflammatory, and respiratory support benefits, particularly due to its flavonoid content.
Preparation & Dosage
General
Traditionally brewed into teas or applied as poultices to treat respiratory issues, indigestion, and inflammation.
General
Modern use includes herbal teas, tinctures, and topical preparations aimed at respiratory wellness and anti-inflammatory relief.
Recommended dose
1–2 tsp dried Tepozán leaf per cup of tea, or follow label instructions for extracts
Nutritional Profile
- Flavonoids (quercetin, kaempferol): Provide antioxidant and anti-inflammatory effects.
- Phenolic compounds: Contribute to antioxidant and anti-inflammatory benefits.
- Vitamin C and E: Offer immune support and cellular protection.
- Essential oils: Contribute to its aromatic and therapeutic properties.
- Trace minerals: Support overall immune function and respiratory health.
How It Works
Mechanism of Action
Verbascoside and linarin, the primary bioactive compounds, exhibit anti-inflammatory effects by suppressing the NF-κB pathway and inhibiting key enzymes including cyclooxygenase and xanthine oxidase. These phenylethanoid glycosides and flavonoids provide hydroxyl radical scavenging activity and DPPH inhibition, with verbascoside showing UVB absorbance at 291 nm and linarin at 334 nm. The compounds demonstrate antibacterial, antiviral, and anticarcinogenic properties through multiple molecular pathways.
Clinical Evidence
Human clinical trials for Tepozán leaf are currently absent, with evidence limited to in vitro and animal studies. In UVB-irradiated SKH-1 hairless mice, B. cordata methanolic extract reduced erythema, sunburn cells, vessel congestion, and epidermal thickening. Cell culture studies showed 49% inhibition of ear edema at 1.6 mg/ear dose via NF-κB inhibition, with cultured cells producing verbascoside at 20.48 ± 1.84 mg/g dry weight compared to 6.20 ± 0.77 mg/g in wild leaves. The current evidence base relies primarily on preliminary phytochemical analyses and ethnobotanical studies rather than controlled human trials.
Safety & Interactions
B. cordata methanolic extract showed no genotoxicity in micronucleus testing and demonstrated skin penetration without reported adverse effects in photoprotection studies. No specific drug interactions or contraindications have been documented in available research. However, general flavonoid-related risks such as enzyme inhibition may apply, though specific interaction data is lacking. Pregnant and nursing women should avoid use due to insufficient safety data, and individuals taking medications metabolized by cytochrome P450 enzymes should consult healthcare providers.
