External Look
The Holarrhena pubescens tree is a medium-sized deciduous tree that can grow up to 10 meters in height.
Bark: The bark is pale gray or grayish-brown, rough, and deeply fissured, with a corky texture. When cut, it exudes a milky latex. The inner bark is a pale yellowish-white.
Leaves: The leaves are opposite, simple, and ovate-oblong with a pointed tip. They are dark green and glossy on the upper surface and slightly hairy on the underside, which is the basis for the specific epithet "pubescens."
Flowers: The flowers are borne in terminal cymes, appearing as a cluster of small, bell-shaped, white flowers. They are highly fragrant and bloom during the spring and summer months.
Fruits: The fruits are long, cylindrical, paired follicles that hang down from the branches. They are typically 20-40 cm long and contain numerous light brown seeds.
Seeds: The seeds, known as "Indrajav," are small, oblong, and have a tuft of silky, white hairs at one end, which aids in wind dispersal.
Healing Properties
Holarrhena pubescens is renowned for its diverse healing properties, with a primary focus on its potent amoebicidal and anti-diarrheal effects. Its medicinal properties are attributed to the presence of various alkaloids, most notably conessine, isoconessine, and kurchine.
Amoebicidal and Antidysenteric: The bark and seeds are highly effective against amoebic dysentery, a severe form of diarrhea caused by the parasite Entamoeba histolytica. The alkaloids, particularly conessine, have a direct inhibitory effect on the growth and activity of this parasite.
Astringent: The bark possesses strong astringent properties, meaning it helps to constrict body tissues and stop the flow of blood or other secretions. This property is crucial in its use for treating hemorrhoids (piles) and bleeding from the gut.
Anthelmintic: Kutaja is effective in expelling intestinal worms (helminths). It is a traditional remedy for parasitic infections.
Carminative: It helps to relieve flatulence and bloating, promoting proper digestion.
Expectorant: The herb helps in expelling phlegm and mucus from the respiratory tract, making it useful in coughs and other respiratory conditions.
Diuretic: It promotes the production of urine, which can be beneficial in certain conditions.
Immunostimulant: The plant possesses potent immunostimulant properties, helping to strengthen the body's immune system and improve its ability to fight off infections.
Skin Diseases: The bark and seeds are used topically and internally to treat various skin diseases (Kushta), including eczema and psoriasis, due to their anti-inflammatory and antiseptic properties.
