अमलतास — India का native yellow cascade (April-June)। Thailand का National Tree! Pod pulp = Aragvadha (Ayurvedic laxative, 2,000 yr)। Anti-fungal confirmed। Fragrant honey। Gulmohar से better urban tree (native, less brittle)।
Amaltas (Cassia fistula) — Amaltas / Golden Shower / Indian Laburnum / Bahawa — is India's most celebrated yellow flowering tree and one of the most medicinally important trees in Ayurveda. The tree produces extraordinary cascading clusters of bright yellow flowers (April-June) that hang like golden curtains — giving it the name "Golden Shower." The visual effect of a mature Amaltas in full bloom — completely covered in hanging yellow flower clusters, each 30-40cm long — is one of India's most breathtaking natural spectacles. Amaltas is also the National Tree of Thailand (called Ratchaphruek) and is central to Thailand's culture and flag symbolism. In Ayurveda, Amaltas is classified as one of the most important laxative trees — the pulp inside the long seed pods (30-60cm) contains anthraquinone compounds that act as gentle laxatives, and this pod pulp has been used in Ayurvedic medicine for thousands of years as Aragvadha in classical formulations. The tree is completely non-toxic for this use — unlike some other laxative plants. Modern phytochemical research has also confirmed significant anti-bacterial, anti-fungal, anti-inflammatory and anti-diabetic activity in various parts of the tree, particularly the leaves and bark.
