== Pharmacological Activities & Therapeutic Efficacy ==
== Pharmacological Activities & Therapeutic Efficacy ==
All findings below are from animal or ''in vitro'' experiments; no controlled human clinical trial was identified during reference checking.
=== Hepatoprotective Activity ===
Aqueous and ethanolic extracts of the stem bark were tested in rats given paracetamol (hepatic injury) or cisplatin (renal injury). The extracts significantly lowered serum SGOT and SGPT activities and serum creatinine and urea levels, indicating a protective effect on liver and kidney in these models.<ref name="Anthony2012">Anthony OE, Francis MA, Philippe EM. Phytochemical screening, and assessment of ameliorating effect of aqueous and ethanolic extracts of Gmelina arborea on drug induced hepatic and renal insufficiency in rats. Pak J Pharm Sci. 2012;25(2):457–461.</ref>
=== Antioxidant Activity ===
Bark and fruit extracts protected liver cells from oxidative stress in an ''in vitro'' liver-slice culture model.<ref name="Sinha2006">Sinha S, Dixit P, Bhargava S, Devasagayam TP, Ghaskadbi S. Bark and fruit extracts of Gmelina arborea protect liver cells from oxidative stress. Pharm Biol. 2006;44(4):237–243.</ref>


=== Hepatoprotective and Antioxidant Efficacy ===
=== Anti-inflammatory and Analgesic Activity ===
''Gmelina arborea'' exhibits significant protective effects on hepatic tissues against toxin-induced oxidative damage.
Aqueous and methanol extracts of the stem bark (500 mg/kg) showed maximum inhibition of carrageenan-induced rat paw oedema of 30.15% and 31.21% respectively. In mice, both extracts prolonged hot-plate latency, and the aqueous extract inhibited acetic-acid-induced writhing by 84.3% (methanol extract 77.9%) at 500 mg/kg. The authors suggest inhibition of prostaglandins and other autacoids as a possible mechanism; this was not directly tested.<ref name="Kulkarni2013">Kulkarni YA, Panjabi R, Patel V, Tawade A, Gokhale A. Effect of Gmelina arborea Roxb in experimentally induced inflammation and nociception. J Ayurveda Integr Med. 2013;4(3):152–157. doi:10.4103/0975-9476.118697</ref>
* '''Mechanism:''' Active constituents enhance the expression of endogenous antioxidant enzymes (such as superoxide dismutase, catalase, and reduced glutathione) while suppressing lipid peroxidation and lowering elevated serum marker enzymes (SGOT, SGPT, ALP).
* '''Scientific Evidence:''' Experimental studies demonstrate that administration of plant extracts markedly preserves structural integrity and functional capability of hepatocytes subjected to hepatotoxins<ref name="Agrawal2007"/>.


=== Anti-Inflammatory and Analgesic Properties ===
=== Wound Healing ===
Traditional claims regarding its efficacy in managing inflammatory conditions and swelling (Sotha) are strongly supported by modern pharmacological models.
An alcoholic extract of the dried leaf powder (200 mg/kg) was studied in incision, excision and dead-space wound models in rats. It increased wound contraction rate, skin and granuloma breaking strength, hydroxyproline content and dry granuloma weight, and shortened the epithelization period, consistent with increased collagen deposition.<ref name="Shirwaikar2003">Shirwaikar A, Ghosh S, Padma GM Rao. Effect of Gmelina arborea Roxb. leaves on wound healing in rats. J Nat Remedies. 2003;3(1):45–48. doi:10.18311/jnr/2003/362</ref>
* '''Mechanism:''' Extracts inhibit key pro-inflammatory mediators, including prostaglandins and histamine, and suppress the cyclooxygenase (COX) pathways.
* '''Scientific Evidence:''' In vivo evaluations using carrageenan-induced paw edema and acute pain models showed significant dose-dependent reductions in inflammation and nociceptive response following administration of ''G. arborea'' extracts<ref name="Billore1995"/>.


=== Wound Healing and Antimicrobial Actions ===
=== Antiulcer Activity ===
Stem bark and leaf preparations are traditionally applied for ulcer management and tissue repair.
Leaves of ''Gmelina arborea'' have been evaluated for anti-ulcer activity in experimentally induced ulcer in Wistar rats.<ref name="Giri2009">Giri M, Divakar K, Goli D, Dighe SB. Anti ulcer activity of leaves of Gmelina arborea plant in experimentally induced ulcer in Wistar rats. Pharmacologyonline. 2009;1:102–110.</ref>
* '''Mechanism:''' Tannins and flavonoids facilitate wound contraction, promote collagen deposition, and exhibit broad-spectrum antimicrobial action against common dermatological and wound-infecting pathogens.
* '''Scientific Evidence:''' Excision and incision wound models treated with root and bark extracts demonstrated accelerated epithelization periods and enhanced tensile strength compared to untreated controls<ref name="Goel2002"/>.


=== Antidiabetic and Renoprotective Potential ===
=== Antidiabetic Activity ===
Aligning with its classical use in managing metabolic imbalances, modern findings indicate favorable blood glucose regulation.
Aqueous bark extract (1.00 g/kg, 30 days) in streptozotocin-induced diabetic rats lowered fasting blood glucose by 37%, reduced HbA1c and fructosamine, raised serum insulin (57%) and C-peptide (39%), improved serum lipids, and histology and immunohistochemistry showed β-cell regeneration in the pancreas.<ref name="Attanayake2016">Attanayake AP, Jayatilaka KAPW, Pathirana C, Mudduwa LKB. ''Gmelina arborea'' Roxb. (Family: Verbenaceae) extract upregulates the β-cell regeneration in STZ induced diabetic rats. 2016 (published 6 Jan 2016), article 4513871. doi:10.1155/2016/4513871. PMCID: PMC4736759</ref>
* '''Mechanism:''' Plant constituents improve peripheral glucose utilization, inhibit key carbohydrate-metabolizing enzymes, and mitigate oxidative stress within renal glomeruli.
* '''Scientific Evidence:''' Administration in experimental diabetic models resulted in significant amelioration of hyperglycemia and attenuation of diabetes-associated renal dysfunction parameters<ref name="Elango2009"/>.


== Safety, Toxicity, and Dosage ==
== Safety, Toxicity, and Dosage ==
* '''Acute Toxicity:''' Toxicological evaluations indicate a favorable safety profile with high oral LD50 thresholds in animal models.
* '''Acute and repeated-dose toxicity:''' Methanol extract of stem bark given orally to mice (300–5000 mg/kg) caused no mortality or significant clinical signs. In a 28-day study in rats (300, 1000 and 2000 mg/kg/day) there were no significant changes in body and organ weights, haematology, clinical chemistry or histology; the reported NOAEL was 5000 mg/kg.<ref name="Kulkarni2012">Kulkarni YA, Veeranjaneyulu A. Toxicological evaluation of the methanol extract of Gmelina arborea Roxb. bark in mice and rats. Toxicol Int. 2012;19(2):125–131. doi:10.4103/0971-6580.97203</ref>
* '''Precautions:''' Use with clinical supervision during pregnancy or lactation, ensuring appropriate dose scaling.
* '''Precautions:''' Reproductive and human safety data were not found in the sources checked; use under clinical supervision, particularly in pregnancy and lactation.
* '''Standard Therapeutic Dosage:'''
* '''Classical dose:''' 20–30 g of crude drug for decoction (see Dose above).
** ''Kwatha (Decoction):'' 20–30 g of raw drug material for decoction preparation<ref name="API1986"/>.

Pharmacological Activities & Therapeutic Efficacy

All findings below are from animal or in vitro experiments; no controlled human clinical trial was identified during reference checking.

Hepatoprotective Activity

Aqueous and ethanolic extracts of the stem bark were tested in rats given paracetamol (hepatic injury) or cisplatin (renal injury). The extracts significantly lowered serum SGOT and SGPT activities and serum creatinine and urea levels, indicating a protective effect on liver and kidney in these models.[6]

Antioxidant Activity

Bark and fruit extracts protected liver cells from oxidative stress in an in vitro liver-slice culture model.[7]

Anti-inflammatory and Analgesic Activity

It increased wound contraction rate, skin and granuloma breaking strength, hydroxyproline content and dry granuloma weight, and shortened the epithelization period, consistent with increased collagen deposition.[9]

Antiulcer Activity

Leaves of Gmelina arborea have been evaluated for anti-ulcer activity in experimentally induced ulcer in Wistar rats.[10]

Antidiabetic Activity

Aqueous bark extract (1.00 g/kg, 30 days) in streptozotocin-induced diabetic rats lowered fasting blood glucose by 37%, reduced HbA1c and fructosamine, raised serum insulin (57%) and C-peptide (39%), improved serum lipids, and histology and immunohistochemistry showed β-cell regeneration in the pancreas.[11]

  • Acute and repeated-dose toxicity: Methanol extract of stem bark given orally to mice (300–5000 mg/kg) caused no mortality or significant clinical signs. In a 28-day study in rats (300, 1000 and 2000 mg/kg/day) there were no significant changes in body and organ weights, haematology, clinical chemistry or histology; the reported NOAEL was 5000 mg/kg.[12]
  • Precautions: Reproductive and human safety data were not found in the sources checked; use under clinical supervision, particularly in pregnancy and lactation.
  • Classical dose: 20–30 g of crude drug for decoction (see Dose above).
