The plant: Centella asiatica (Gotu Kola)
Centella asiatica is a creeping, perennial plant from the Apiaceae (parsley) family. It grows primarily in tropical and subtropical regions of Asia – in India, Sri Lanka, Indonesia and parts of Africa. The plant favours moist, shaded locations and forms small, kidney-shaped leaves with delicate purple flowers.
In the Ayurvedic tradition, Centella asiatica is known as "Brahmi" or "the herb of the mind" and is traditionally valued for its role in meditation and mental clarity. It also has a long history in Traditional Chinese Medicine. The name "Gotu Kola" comes from Sinhalese and literally means "cone-shaped leaf".
The entire aerial part of the plant is used for extraction – leaves and stems contain the valuable triterpene saponins.

Frequently Asked Questions (FAQ)
What does "1:1 extraction ratio" mean?
It means: one kilogram of plant material produces one litre of extract. This is the most concentrated ratio possible for a hydroalcoholic liquid extract and ensures that the complete active compound profile of the plant is preserved.
Why does the extract contain alcohol?
The alcohol (30% vol.) serves as a natural solvent that dissolves the valuable triterpene saponins of Centella particularly well — both water-soluble and fat-soluble compounds. At the same time, it provides natural preservation without artificial additives. The amount of alcohol per dose (5-10 drops) is minimal.
What sets this extract apart from Centella capsules or powder?
The liquid extract prepared using the extraction ratio 1:1 offers high concentration with simple dosing. Powder is suited for smoothies, tea is traditional but less concentrated. The liquid extract combines tradition and practicality.
Which size should I choose?
The 30 ml size is ideal for trying or for a short cycle. The 100 ml size offers better value for regular use.
Is the extract vegan?
Yes – it contains only Centella asiatica and alcohol. No animal-derived ingredients.
How should I store the extract?
Keep away from light and heat sources. Refrigeration is not necessary. The amber glass bottles provide additional protection.
