Clerodendrum phlomidis

Clerodendrum phlomidis is a medicinal plant from Siddha medicine containing bioactive compounds that demonstrate anti-inflammatory effects through lysosomal membrane stabilization. Research shows preliminary evidence for blood glucose reduction and anticancer activity against oral cancer cells.

Origin & History

Clerodendrum phlomidis is a medicinal plant from the Verbenaceae family, native to India and traditionally used in Ayurvedic and Siddha medicine systems. The primary therapeutic component is extracted from its leaves using alcoholic, aqueous, ethanolic, or methanolic solvent extraction methods.

Historical & Cultural Context

Clerodendrum phlomidis has been used for centuries in Indian traditional medicine systems, particularly by tribal communities in southern India's Nilgiris region. Traditional applications include treating inflammation, diabetes, asthma, rheumatism, digestive disorders, and as a bitter tonic during measles recovery in children.

Health Benefits

• Anti-inflammatory and antiarthritic effects demonstrated in animal models through lysosomal membrane stabilization (preliminary evidence)
• Blood glucose reduction shown in alloxan-induced diabetic rats at 100-200 mg/kg doses (preliminary evidence)
• Anticancer activity against oral cancer (HSC-3) and renal carcinoma (ACHN) cells with <50% cell survival after 24 hours (in vitro evidence only)
• Antibacterial properties through secondary metabolite release (in vitro evidence only)
• Traditional use for respiratory conditions including asthma and fever (traditional evidence only)

How It Works

Clerodendrum phlomidis exerts anti-inflammatory effects through lysosomal membrane stabilization, preventing cellular damage and reducing inflammatory responses. The plant's bioactive compounds demonstrate glucose-lowering activity in diabetic animal models, likely through enhanced insulin sensitivity or glucose metabolism pathways. Anticancer mechanisms involve cytotoxic activity against HSC-3 oral cancer cells, though specific molecular targets require further investigation.

Scientific Research

Current research on Clerodendrum phlomidis is limited to preclinical studies with no human clinical trials identified. Key studies include an in vitro nanofiber study (PMID: 35855787, later retracted) showing anticancer effects, and an animal antiarthritic study (PMID: 21527330) demonstrating anti-inflammatory properties in rat models.

Clinical Summary

Current evidence for Clerodendrum phlomidis is limited to preliminary animal studies and in vitro research. Anti-inflammatory and antiarthritic effects were demonstrated in animal models through lysosomal membrane stabilization mechanisms. Blood glucose reduction was observed in alloxan-induced diabetic rats at doses of 100-200 mg/kg body weight. Anticancer activity has been shown specifically against HSC-3 oral cancer cell lines in laboratory studies, but human clinical trials are lacking.

Nutritional Profile

Clerodendrum phlomidis (commonly known as 'Agnimantha' or 'Turpeth') has limited systematic nutritional profiling, but phytochemical analyses reveal the following: Bioactive compounds include clerodendrin A and B (diterpenoid glycosides, primary active constituents), phlomidoside (iridoid glycoside), scutellarein and hispidulin (flavonoids identified in leaf extracts), luteolin and apigenin (flavone aglycones present in aerial parts), and alkaloids including clerodin. Phenolic content reported at approximately 15-25 mg gallic acid equivalents per gram of dry extract in methanol extracts. Flavonoid content estimated at 8-14 mg quercetin equivalents per gram of dry extract. The plant contains tannins (condensed and hydrolyzable forms), saponins, and terpenoids including betulinic acid and oleanolic acid in bark and root fractions. Sterols including beta-sitosterol and stigmasterol have been identified. Crude fiber content in leaves is moderate (estimated 8-12% dry weight based on related Clerodendrum species). Protein content in leaves is approximately 10-15% dry weight. Mineral content includes potassium, calcium, and iron, though precise concentrations are not well-documented in peer-reviewed literature. Essential oils from leaves contain alpha-pinene, beta-caryophyllene, and germacrene-D. Bioavailability data is largely absent; lipophilic terpenoids and flavonoid aglycones are expected to have moderate oral bioavailability, while glycosidic forms require gut microbial hydrolysis for activation.

Preparation & Dosage

Based on animal studies only: ethanol leaf extract at 100-200 mg/kg body weight orally for 7 days showed antidiabetic effects in rats. No human dosages have been established through clinical trials. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

Safety & Interactions

Safety data for Clerodendrum phlomidis in humans is extremely limited due to lack of clinical trials. Potential interactions with diabetes medications may occur given its glucose-lowering effects in animal studies. Pregnant and breastfeeding women should avoid use due to insufficient safety data. Individuals with existing medical conditions or taking medications should consult healthcare providers before use, particularly those on blood glucose-lowering drugs.
