'''[https://en.wikipedia.org/wiki/Centella_asiatica Hydrocotyle asiatica L.]''' (syn. ''Centella asiatica'' (L.) Urb.), popularly known as '''Mandukaparni''' (Gotu Kola), is a small, herbaceous, creeping plant belonging to the family Apiaceae. It is highly revered in [[Ayurveda]] as a potent ''Medhya'' (intellect-promoting) drug and ''Rasayana'' (rejuvenative), traditionally utilized for enhancing cognitive functions, supporting neurological health, and purifying the blood. | |||

In traditional Ayurvedic texts, Mandukaparni is classified under ''Vayasthapana'' (anti-ageing) and ''Tikta Skandha'' (group of bitter drugs). It possesses a bitter taste (''tikta rasa''), cold potency (''sheeta veerya''), sweet post-digestion effect (''madhura vipaka''), and light qualities (''laghu guna''). It acts primarily as a brain tonic (''medhya'') and pacifies Kapha and Pitta doshas.<ref name="ref2"/> | |||

== 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.<ref name="wattanathorn2008"/> | |||
=== 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.<ref name="shukla1999"/> | |||
* '''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"/> | |||
== 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.<ref name="chivapat2011"/> | |||
* '''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.<ref name="ref1"/> | |||
== 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.<ref name="brinkhaus2000"/> | |||

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
| 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] |
