Health benefits of Pagoda Tree

Styphnolobium japonicum (previously Sophora japonica) popularly known as the Japanese pagoda tree, Chinese scholar tree or pagoda tree is a species of plant in the subfamily Faboideae in the Fabaceae / Leguminosae (Pea family). The plant is known by an assortment of common names: Japanese Pagoda Tree, Umbrella Tree, Chinese Scholar Tree, or sometimes more simply as Pagoda Tree or Scholar Tree. In contradiction to its botanical name, the Pagoda Tree is actually native to East Asia—central and northern China Japan and Korea for thousands of years, but now extensively cultivated in temperate and subtropical regions of the world, and rarely in highlands in the tropics, in South-East Asia at least in Vietnam and Thailand. It is a popular ornamental plant in Europe, North America and South Africa.

The plant is formerly known as Sophora japonica. Specific epithet means of Japan but this tree is not native to Japan. The tree gets its name from tradition of being planted around Buddhist temples. Some of the original pagoda trees in the gardens at Kew were planted near to the Pagoda (built in 1761), presumably because of their Chinese origins and its common name. In folklore, it is said that a cowherd once built a home out of this species of tree. Within a month his whole family was suddenly found dead. It was therefore believed that demons are drawn to this tree and it is therefore not suitable to use its wood to build homes. In addition, in the wild, other species of tree rarely grow near it. It is still popular as an ornamental, due to its showy inflorescences (flowering panicles) of creamy white flowers. The plant is harvested from the wild for local use as a food, medicine and source of materials. It is cultivated for medicinal purposes and as a source of rutin, and is also commonly grown as an ornamental. The flower buds were formerly traded as a dyestuff for the batik industry.

Pagoda Tree Facts

Plant Description

Pagoda-tree is a small to medium-sized, deciduous perennial round-headed tree that normally grows about 65 ft. tall. It has a rapid growth rate and tolerates city conditions, heat, and drought. When grown in a yard, the Chinese Pagoda Tree can reach a height of 50-75 ft.; however, when grown along the road in compact soil, it only grows to 30-40 ft. The tree has a short stout bole, upright, spreading branches and glabrous, terete, pale green, lenticillate twigs and broad round crown. The young stems are slender, with prominently protruding nodes and smooth gray-green bark which provides some winter interest. The bark of mature trunks and branches becomes furrowed into fibrous, interlaced, scaly ridges, gray and corrugated. Young wood is smooth, dark gray-green. Old branches and trunk gradually take on rugged look of oak.

Leaves

The Pagoda tree’s leaves are pinnately compound, 6-10 inches long, composed of 7 to 17 ovate leaflets, each 1-2 inches long and about half as wide. The leaves are deep green and lustrous above and glaucous pale green beneath. The bright green leaf color lasts well into the fall (to mid-November in the Boston area), when the leaves turn yellow very briefly and drop almost immediately. The leaves are extremely pest-free.

Leaf arrangement	Alternate
Leaf type	Odd pinnately compound
Leaflet margin	Entire
Leaflet shape	Ovate
Leaflet venation	Pinnate
Leaf type and persistence	Deciduous
Leaflet blade length	Less than 2 inches
Leaf color	Green
Fall color	Yellow

Flower

Styphnolobium japonicum apparently does not flower when young; flowering normally only commences when the tree is 30-40 years old. Its flowers are certainly one of its most notable features. Flowers are lightly fragrant, pale, creamy yellow to greenish-white, and about 1/2 inch long, they cover the tree in abundant pyramid-shaped terminal panicles up to 12 inches across. Old trees flower freely, especially after hot summers. Most flowers fall early to form a dense, white carpet on the ground. The pagoda tree at Kew usually flowers in September, whereas in its native China it flowers in August/September and fruits in October/November. Chinese Scholar Tree is planted as an ornamental tree in Kashmir.

Flower color	White; yellow
Flower characteristics	Showy; summer flowering

 

Fruits

The fertile flowers are followed by clusters of slender, leguminous pods that range from 2 to 4 inches long, containing 1 to 6 seeds. Each pod is constricted between the individual seeds in a way that resembles a string of beads. In the fall, the light-green pods make delicate filigree against the dark green leaves, and after the leaves drop, the pods turn olive green and remain on the tree, sometimes remaining throughout the winter. Seeds are ellipsoid to ovoid, 8 mm long and 4–5 mm wide, slightly compressed and yellowish-brown colored.

Fruit shape	Elongated; pod
Fruit length	6 to 12 inches; 3 to 6 inches
Fruit covering	Dry or hard
Fruit color	Brown; yellow
Fruit characteristics	Does not attract wildlife; fruit, twigs, or foliage cause significant litter; persistent on

 

Health benefits of Pagoda Tree

Listed below are some of the popular health benefits of using pagoda tree on our regular routine

1. Hemorrhoids

Hemorrhoids are normally categorized by swollen and uncomfortable blood vessels around the anus. It is an unpleasant, but an extremely common concern. Topical creams, ointments, and cushions are common therapies but many people reasonably prefer herbal remedies that promote venous health, rather than simply temper unpleasant symptoms.

The beneficial compounds contained within Pagoda-tree may make it one of the best herbal supplements for hemorrhoids. Troxerutin has vaso-protective properties and is a therapy for hemorrhoids. Oxymatrine is known to help reduce the swelling associated with unhealthy blood vessels.

2. Cardiovascular Health

Although Pagoda-tree promotes healthy blood vessels, it also encourages overall cardiovascular system health. It supports normal heartbeat and helps create an environment that’s less susceptible to blood clot formation. Initial animal research suggests that oxymatrine may even protect the heart and improve its functionality.
