Enhance Memory, Reduce Anxiety & Promote Neurogenesis with Gotu Kola
Gotu Kola (Centella Asiatica), known as the “student herb” in Bali, has been used for millennia in Ayurveda and Traditional Chinese Medicine to sharpen the mind, improve memory, and reduce stress. Native to Southeast Asia’s wetlands, this adaptogenic herb supports cognitive clarity, neuroprotection, and balanced mood. Its active compounds—asiaticoside, asiatic acid, and madecassic acid—stimulate dendritic growth, protect neurons from oxidative stress, and regulate key neurotransmitters like GABA and acetylcholine.
Whether you’re a student preparing for exams, a professional navigating high-pressure work, or anyone seeking to maintain brain health as you age, Gotu Kola offers a gentle yet powerful boost. Explore its mechanisms, dosage guidelines, clinical research, and real user feedback below to see why this “living brain tonic” deserves a place in your daily regimen.

Gotu Kola (Centella Asiatica) is an herbaceous perennial plant native to wetlands in Southeast Asia. In Ayurveda, it’s known as “Brahmi” and is celebrated for enhancing memory, supporting mental clarity, and reducing anxiety. Traditional Chinese Medicine also values it for healing skin wounds and calming the spirit. The herb contains potent triterpenoids—asiaticoside, madecassoside, asiatic acid, and madecassic acid—along with flavonoids and essential vitamins that collectively promote neurogenesis, neuroprotection, and balanced neurotransmitter activity.
Mechanisms of Action
| Mechanism | Action |
|---|---|
| Neurogenesis | Stimulates growth of dendrites and axons in neurons, enhancing brain plasticity and connectivity. |
| Neuroprotection | Protects neurons from oxidative stress, heavy metals, and toxins via antioxidant triterpenoids. |
| Neurotransmitter Regulation | Inhibits acetylcholinesterase, increasing acetylcholine levels; enhances conversion of glutamate to GABA, supporting calm focus. |
| Cerebral Blood Flow | Improves microcirculation in the brain, delivering more oxygen and nutrients for optimal function. |
| Stress Reduction | Modulates the HPA axis, lowering cortisol levels and easing anxiety/stress responses. |
These synergistic pathways make Gotu Kola a comprehensive nootropic: promoting new neural connections, safeguarding existing neurons, and balancing mood-supporting neurotransmitters.

Core Benefits
- Improves Memory & Learning Ability: Enhances short-term recall, verbal fluency, and retention—ideal for students and professionals.
- Neuroprotection: Shields brain cells from oxidative damage, heavy metals, and toxins; supports long-term cognitive longevity.
- Enhances Cerebral Blood Flow: Increases nutrient and oxygen delivery to neurons, boosting mental energy and clarity.
- Reduces Anxiety & Stress: Elevates GABA levels and modulates cortisol, producing a calm yet alert state of mind.
- Boosts Acetylcholine Levels: Inhibits acetylcholinesterase, preventing acetylcholine breakdown and supporting memory formation.
- Stimulates Neural Growth: Promotes dendritic sprouting and axonal repair; helps form new neural pathways for improved cognition.
Scientific Studies
Working Memory & Mood (Thai Clinical Trial)
- A randomized trial in Thailand administered 250–750 mg/day of Gotu Kola extract to 80 adults over 8 weeks, resulting in significant improvements in working memory, recall speed, and mood scores compared to placebo.
Neurogenesis in Animal Models
- Animal studies found that Gotu Kola extract increased dendritic growth by over 100% in hippocampal neurons and accelerated axon repair after induced neural injury.
Telomerase Activation (2019 Study)
- A 2019 in vitro study showed Gotu Kola increased telomerase activity 8.8-fold in human fibroblasts, suggesting potential anti-aging and DNA repair effects.
Dosage Guide
| Form | Dosage | Notes |
|---|---|---|
| Standardized Extract | 50–250 mg, 2–3 times/day | Extracts should contain ~40% asiaticoside, ~30% asiatic acid, ~30% madecassic acid, and 1–2% madecassoside. |
| Gotu Kola Powder | 400–450 mg/day | Mix into smoothies or tea; start with lower dose and adjust based on tolerance and cognitive response. |
| Tincture (1:2, 30% alcohol) | 30–60 drops (1.5–3 mL), 3 times/day | Hold sublingually for 30 seconds before swallowing for faster absorption; can be taken with a small snack. |
For best results, cycle Gotu Kola use (e.g., 5 days on, 2 days off) or take a 1–2 week break every 2 months to prevent tolerance. Combine with a healthy diet, good sleep, and stress-management practices to optimize outcomes.
Side Effects & Warnings
Gotu Kola is generally well-tolerated, but potential adverse effects include:
- Mild Skin Irritation: Topical use may cause itching or rash in sensitive individuals; discontinue if irritation occurs.
- Headache & Nausea: Rare at higher doses; split dosage or reduce if symptoms appear.
- Dizziness & Drowsiness: May occur in some users—avoid operating heavy machinery if affected.
- Liver Toxicity: High doses over extended periods could stress liver function; monitor liver enzymes if using long-term.
Important: Consult a healthcare provider before use if pregnant, breastfeeding, or on medications—especially sedatives, antihypertensives, or thyroid medications. Discontinue use if any severe adverse reactions occur.
How It Feels
Gotu Kola’s effects are gradual and subtle. Commonly reported subjective experiences include:
- Gentle Mental Clarity: A feeling of “mental lift” without jitteriness—ideal for long study sessions or demanding work.
- Calm Alertness: Reduced anxiety and racing thoughts while maintaining focus and motivation.
- Enhanced Memory Recall: Better retention of facts, names, and details—especially noticeable in learning environments.
- Improved Sleep Quality: Some users report deeper, more restful sleep and occasional lucid dreaming when taken in the evening.
- Balanced Mood: A grounded, even‑keeled sense of well-being—helpful for stress management and emotional resilience.
Peak benefits often emerge after 4–6 weeks of consistent use. Results depend on individual biochemistry, diet, and lifestyle factors. Combining Gotu Kola with other nootropics like Lion’s Mane or Bacopa Monnieri can produce synergistic cognitive effects.
