Question 1

What family does Gaertnera vaginans belong to?

Accepted Answer

Gaertnera vaginans belongs to the Rubiaceae family, a large family of flowering plants that includes many species of medicinal, ecological, and economic significance. Members of this family are found across tropical and subtropical regions worldwide, and Sri Lanka hosts numerous native representatives.

Question 2

Is Gaertnera vaginans ssp.vaginans found only in Sri Lanka?

Accepted Answer

The genus Gaertnera occurs across tropical Asia and Africa, but the subspecies vaginans as documented in Sri Lanka's ayurvedic plant catalogue is associated with the island's specific forest environments. Its precise range across the broader region requires confirmation through current taxonomic and herbarium records.

Question 3

What is the significance of Sri Lanka's ayurvedic plant catalogue?

Accepted Answer

Sri Lanka's ayurvedic plant catalogue is a systematically compiled record of native and naturalised plant species used in traditional indigenous medicine. It reflects over two thousand years of documented plant knowledge and remains a reference for both traditional practitioners and modern pharmacological researchers.

Question 4

Where can I learn about medicinal plants in Sri Lanka as a visitor?

Accepted Answer

The Royal Botanic Gardens at Peradeniya near Kandy is one of the best places to explore Sri Lanka's plant diversity, including many species with medicinal uses. Eco-lodges in the wet zone and guided nature walks in forest reserves such as Sinharaja also offer introductions to traditional herbal knowledge.

Question 5

Are ayurvedic plants in Sri Lanka protected by law?

Accepted Answer

Several native plant species in Sri Lanka, particularly those found in protected forest areas, are safeguarded under the Forest Conservation Ordinance and related legislation. The collection of plants from national parks and reserves without authorisation is prohibited, helping to protect rare and medicinally significant species in the wild.

Question 6

What does ssp.vaginans mean in the plant name?

Accepted Answer

The abbreviation ssp. stands for subspecies, indicating a taxonomic rank below species that distinguishes populations with consistent, inherited differences from other members of the same species. In this case, vaginans is both the species and subspecies name, making it the nominate or type subspecies — the form that was first formally described when the species was classified.

Question 7

How are Sri Lanka's medicinal plants used in ayurvedic treatments?

Accepted Answer

Ayurvedic preparations in Sri Lanka use plant parts including bark, roots, leaves, seeds, and resins, typically processed into decoctions, powders, oils, or pastes. Different plants target different body systems, and a practising ayurvedic physician selects combinations based on the individual's constitution and condition. Some preparations have been in continuous use for more than a thousand years.
