== Phytochemical Composition ==
== Phytoconstituents ==
The therapeutic efficacy of ''Hydrocotyle asiatica'' (*Centella asiatica*) is attributed to a rich profile of bioactive secondary metabolites:
The active constituents of ''Centella asiatica'' are pentacyclic triterpene derivatives, chiefly the asiaticosides and madecassosides, which have been the focus of most chemical and pharmacological investigation of the plant.<ref name="brinkhaus2000"/>
* '''Triterpenoid Saponins (Centelloids):''' Asiaticoside, madecassoside, asiatic acid, and madecassic acid, responsible for most neuroprotective and wound-healing actions.
* '''Flavonoids & Phenols:''' Quercetin, kaempferol, and rutin acting as powerful antioxidants.
* '''Volatile Oils & Amino Acids:''' Essential oils, vallerine, and various free amino acids.


== Pharmacological Activities & Therapeutic Efficacy ==
== Pharmacological Activities & Therapeutic Efficacy ==
=== Pro-Cognitive and Neuroprotective Effects ===
Mandukaparni is globally recognized as a premier *Medhya* (nootropic) herb that enhances memory, learning, and neurological functions.
* '''Mechanism:''' Triterpenoids stimulate nerve growth factor (NGF) synthesis, protect neurons against amyloid-beta induced toxicity, and modulate central neurotransmitter pathways.
* '''Scientific Evidence:''' Experimental and clinical studies confirm that standardized extracts significantly improve cognitive performance, spatial memory retention, and mitigate neurodegenerative oxidative stress.<ref name="Gohil2010">{{cite journal |last1=Gohil |first1=K.

=== Wound Healing and Dermatological Efficacy ===
=== Cognitive Function and Mood (''Medhya'') ===
Its traditional application in chronic skin conditions (*kustha*) and tissue regeneration is strongly validated by modern science.
Mandukaparni is classified in Ayurveda as a ''Medhya'' (intellect-promoting) drug, and its effect on cognition has been tested in a human trial.
* '''Mechanism:''' Asiaticoside promotes collagen synthesis, stimulates fibroblast proliferation, and enhances angiogenesis at wound sites.
* '''Scientific Evidence:''' In a randomized, double-blind, placebo-controlled study, 28 healthy elderly volunteers received a ''Centella asiatica'' extract at 250, 500 or 750 mg once daily for 2 months. The high dose improved working memory and increased the N100 amplitude of the event-related potential, and self-rated mood also improved.<ref name="wattanathorn2008"/>
* '''Scientific Evidence:''' Research demonstrates that topical and systemic administration accelerates epithelialization, enhances tensile strength in scars, and improves microcirculation in venous insufficiency models.<ref name="Shukla1999b">{{cite journal |last1=Shukla |first1=A. |last2=Rasik |first2=A.

=== Anti-Inflammatory and Anxiolytic Actions ===
=== Wound Healing and Skin (''Kustha'') ===
Mandukaparni exhibits profound systemic anti-inflammatory and stress-relieving properties.
The traditional use of Mandukaparni in skin disease and tissue repair has been examined with its main triterpene glycoside, asiaticoside.
* '''Mechanism:''' Suppresses pro-inflammatory cytokines and modulates GABAergic systems to reduce anxiety and stress responses.
* '''Scientific Evidence:''' Topical 0.2% asiaticoside in guinea pig punch wounds increased hydroxyproline by 56% and tensile strength by 57%, and gave higher collagen content and better epithelialisation. In streptozotocin-diabetic rats with delayed healing, 0.4% asiaticoside improved the same parameters. It was also active orally at 1 mg/kg in guinea pigs.<ref name="shukla1999"/>
* '''Scientific Evidence:''' Preclinical trials indicate marked reductions in anxiety indices and notable systemic anti-inflammatory responses comparable to standard reference compounds.<ref name="Bylka2013">{{cite journal |last1=Bylka |first1=W. |last2=Znajdek-Awizen |first2=P. |last3=Stelich |first3=E. |year=2013 |title=Centella asiatica in cosmetology |journal=Postepy Dermatologii i Alergologii |volume=30 |issue=1 |pages=46–49}}</ref>
* '''Mechanism:''' Asiaticoside promoted angiogenesis in the chick chorioallantoic membrane model at 40 µg/disk.<ref name="shukla1999"/>
 
=== Anxiolytic Action ===
* '''Scientific Evidence:''' In a double-blind, placebo-controlled study of 40 healthy volunteers (20 per group), a single 12 g oral dose of Gotu Kola significantly reduced the peak acoustic startle response at 30 and 60 minutes compared with placebo. It had no significant effect on self-rated mood, heart rate or blood pressure. The authors described the findings as preliminary evidence of anxiolytic activity.<ref name="bradwejn2000"/>

Phytoconstituents

The active constituents of Centella asiatica are pentacyclic triterpene derivatives, chiefly the asiaticosides and madecassosides, which have been the focus of most chemical and pharmacological investigation of the plant.[3]

Pharmacological Activities & Therapeutic Efficacy

Cognitive Function and Mood (Medhya)

Mandukaparni is classified in Ayurveda as a Medhya (intellect-promoting) drug, and its effect on cognition has been tested in a human trial.

  • Scientific Evidence: In a randomized, double-blind, placebo-controlled study, 28 healthy elderly volunteers received a Centella asiatica extract at 250, 500 or 750 mg once daily for 2 months. The high dose improved working memory and increased the N100 amplitude of the event-related potential, and self-rated mood also improved.[4]

Wound Healing and Skin (Kustha)

The traditional use of Mandukaparni in skin disease and tissue repair has been examined with its main triterpene glycoside, asiaticoside.

  • Scientific Evidence: Topical 0.2% asiaticoside in guinea pig punch wounds increased hydroxyproline by 56% and tensile strength by 57%, and gave higher collagen content and better epithelialisation. In streptozotocin-diabetic rats with delayed healing, 0.4% asiaticoside improved the same parameters. It was also active orally at 1 mg/kg in guinea pigs.[5]
  • Mechanism: Asiaticoside promoted angiogenesis in the chick chorioallantoic membrane model at 40 µg/disk.[5]

Anxiolytic Action

  • Scientific Evidence: In a double-blind, placebo-controlled study of 40 healthy volunteers (20 per group), a single 12 g oral dose of Gotu Kola significantly reduced the peak acoustic startle response at 30 and 60 minutes compared with placebo. It had no significant effect on self-rated mood, heart rate or blood pressure. The authors described the findings as preliminary evidence of anxiolytic activity.[6]

Safety, Toxicity, and Dosage

  • Acute toxicity (animal study): A single oral dose of 10 g/kg of a standardized Centella asiatica extract (ECa 233) given to mice caused no toxic signs and no deaths during the observation period.[7]
  • Precautions: Use under the guidance of a qualified Ayurveda physician, particularly in chronic conditions or when taking conventional medicines.
  • Standard Therapeutic Dosage: Whole plant powder (churna) 3–6 g daily or as directed by an Ayurveda physician.[1]

Research Gaps

Centella asiatica has been investigated more extensively than most medicinal plants, with clinical evidence mainly for venous insufficiency, striae gravidarum and wound healing disturbances. Clinical studies on its sedative, analgesic, antidepressive, antimicrobial, antiviral and immunomodulatory effects, which have been shown experimentally, are still lacking.[3]

Summary of Therapeutic Profile

Experimental evidence for Centella asiatica
Indication Preparation studied Model Principal finding Reference
Cognitive function / Medhya Plant extract (250–750 mg/day) Healthy elderly volunteers (RCT, 2 months) Improved working memory and self-rated mood at the high dose [4]
Wounds & skin diseases / Kustha Asiaticoside (topical and oral) Guinea pig and diabetic rat wounds Higher hydroxyproline, tensile strength, collagen and epithelialisation [5]
Anxiety / stress Gotu Kola, single 12 g oral dose Healthy volunteers (RCT) Reduced acoustic startle response [6]
