Facts about Stinking Cassia

Stinking Cassia scientifically known as Senna tora (originally described by Linnaeus as Cassia tora) is a plant species belonging to family Fabaceae and the subfamily Caesalpinioideae. The plant is native to Indian sub-continent (i.e. India, Bhutan, Nepal, eastern Pakistan and Sri Lanka), southern China, south-eastern Asia (i.e. Cambodia, Laos, Myanmar, Thailand, Vietnam, Indonesia, Malaysia, the Philippines and Papua New Guinea) and parts of western Polynesia (i.e. the Solomon Islands). It is considered invasive in New-Caledonia. Its name is derived from its Sinhala name tora. Most common English name is sickle senna and sickle wild sensitive-plant. Other popular common names include Java bean, foetid cassia, low senna, peanut weed, sicklepod, stinking cassia, Chinese senna, tora, coffee pod, sicklepod senns and wild senna. It is often confused with Chinese senna or sicklepod, Senna obtusifolia.

Whole plant, leaves, seeds and roots have been extensively used in traditional Indian and South Asian medicine. The plant is gathered from the wild for local use as a food and medicine. It is occasionally grown for its seeds, which are normally used as a mordant. Its tea has been referred as coffee-tea, because of its coffee like aroma and taste. Apart from that it is also used as natural pesticide in organic farms, and as a powder commonly used in the pet food industry. Since it has an external germicide and anti-parasitic character, it has been used for treating several skin diseases like psoriasis, ringworm, leprosy, itching and also for snakebites.

Stinking Cassia Facts

Plant Description

Stinking Cassia is a small erect hairless, annual to perennial plant that normally grows about 50-150 cm tall, but sometimes growing up to 2.5 m in height. The plant occurs abundantly in open pastures, in pastures under coconuts, mountain slopes, roadsides, wasteland, river bank sands, disturbed sites, waterways and also pastures in wetter tropical and sub-tropical environments. The plant prefers deep, well-drained, moderately fertile sandy loam and tolerates fairly low soil fertilities and moisture levels. True to its name, foetid/stinking cassia has an unpleasant smell. It is broadly spreading with several ascending, hairless branches. The branched, sprawling, stems are usually hairless or sparsely hairy.

Leaves

Compound leaves of the plant are arranged alternately along the stems and are borne on fairly long petioles which are about 20-45 mm long. 50-75 mm long leaves have about two to four pairs of leaflets that are egg-shaped in outline with narrower end attached to the stalk. Leaflets are 10-55 mm long and 10-35 mm wide and have rounded tips and their margins are lined with tiny hairs. Small elongated structure is usually located between each of the lowest two pairs of leaflets. Leaves give off a strong unpleasant odor, mostly when damaged or brushed against.

Flowers

The yellow flowers are borne on 6-10 mm long stalks. These flowers are arranged in pairs in the leaf forks and are mostly found near the tips of the branches. Each flower consists of five sepals, five yellow petals (8-10 mm long) and seven fertile stamens with small anthers (1.5-2.5 mm long). Flowering occurs mostly from late summer through to early winter.

Fruit & Seeds

Fertile flowers are followed by a very slender, sickle-shaped pod that is 12-25 cm long and 2-6 mm wide. It is nearly round in cross-section and curved downwards. Fruits are initially green turning to brownish-green as they mature and are slightly concave between each of the seeds (i.e. the pods are slightly separate). There are 30–50 seeds within a pod. Seeds are striped olive and brown about 3 mm long, shiny in appearance, and flattened or irregularly shaped.

Stinking Cassia has several uses. The plant and seeds are edible. Young leaves can be cooked as a vegetable while the roasted seeds are used as a substitute coffee. Flowers are added to food in Sri Lanka. It is mixed with guar gum for use in mining and other industrial applications.
