Leaves and fruits 1 https://vitaforest.eu/en/cassia-wiki.html 10/1/21 Description Specification & Spread Senna (cassia) leaves — folia sennae (folia cassiae) Senna fruits — fructus sennae Alexandrine senna — cassia acutifolia delile ( = senna alexandrina mill.) Bean family (Senna family) – fabaceae (caesalpinioideae) Other names: Alexandria senna, cassia. It is a small xerophytic shrub from 0.5 to 1 m tall. The stem is branched, the lower branches are long, creeping along the ground. The leaves are alternate, large, pinnately-compound from 4-5 pairs of folioles, with styrous stipules. The folioles are oblong-lanceolate, entire, slightly uneven at the base, anastomosing veins are clearly visible along the edge. The flowers are yellow, slightly zygomorphic, pentamerous, collected in axillary brush. The fruit is a flat wide elliptic webbed dry greenish-brown and polyspermic bean. It blooms from late June to autumn, the seeds ripen from September. Naturally it grows in desert and semi-desert areas of Northern and Middle Sudan, on the coast of the Red Sea, in the Nubian Desert, Southern Arabia and Somalia. It is cultivated in India and Pakistan. It is cultivated in specialized farms of South Kazakhstan (Chimkent region) and in Turkmenistan in the form of annual crop. Composition The leaves and fruits of Alexandrine senna contain the amount of anthracene derivatives consisting of: simple monomers and their glycosides, as well as di- and heterodiantrons (sennosides A, B, C, D, and aglycones - corresponding sennidins). Its content in leaves is up to 6%, in fruits - 2.7%. The flavonoids are represented by derivatives of kampferol and isorhamnetin. There are mucus and tar. The resinous substances present in the leaves of cassia cause pain in the intestines, are released from them when filtering the prepared infusions after complete cooling, in a cold form the resin precipitates and remains on the filter. In the preparation of fees with cassia leaves from resinous substances get rid of the pre-soak in alcohol. The resinous substances are absent in fruits. Harvesting and storage of raw materials Harvesting. The leaves are harvested by hand 2-3 times per season. The last time the whole plant is mown, the separate leaves of a compound leaf are torn off. The fruit harvesting on seed plantations is carried out manually as they mature. Drying. It is dried in the shade, under a canopy, turning the raw material several times. Storage. It is stored in pharmacies - in well-closed boxes, in stock - in bales or piles in a dry and well- ventilated room, fruits - in a special pantry for fruits and seeds. 2 https://vitaforest.eu/en/cassia-wiki.html 10/1/21 External signs of raw materials Leaves Whole raw materials. There are separate leaves and petioles of a complex parotid leaf, whole or partially crushed, pieces of thin herbaceous stems, buds, flowers and unripe fruits. The small leaves are oblong-lanceolate and pointed to the apex. It is wide in the middle part, at the base it is unequal, thin, brittle, entire with a very short petiole. The lateral veins of the first order are clearly visible on both sides. It is diverged at an acute angle from the main vein and interconnected by arcs running parallel to the edge of the small leaf. The leaf length is 1-3 cm, the width is 0.4-1.2 cm. The fruit is a bean that is flat, leathery, slightly curved, 3-5 cm long and 1.5-2 cm wide.

The colour is grayish green. The taste is slightly bitter with a sensation of sliminess. Fruit It is flat, thin, leathery, slightly curved or slightly reniform beans, rounded at the apex with a slight remaining stab, narrowed to the base. It is 3-6 cm long and 1.5-2 (2.5) cm wide. The glumes are dry and membranous. Each fruit contains up to 6 seeds. The seeds are net-wrinkled, flat, heart-wedge-shaped or almost quadrangular in outline. The colour of the fruit is light green, in the middle it is brown. The taste is bitter. Properties and application The cassia leaves have laxative properties, it increases the motor function of the large intestine due to irritation of the receptors of the mucous membrane, reflexively increasing peristalsis, which leads to faster emptying and restoration of the normal functioning of the intestine. The action comes after 6-12 hours after administration. The prolonged use can lead to atrophy of the smooth muscles of the colon and the violation of its innervation. Senna can be used in violation of the flow of bile into the intestine. Application of cassia The senna leaves are one of the fixed assets used on all continents as a laxative. Cassia is used for habitual constipation, before surgery, for postoperative intestinal atony. Contraindications Hypersensitivity to the preparation, perforated ulcer, intestinal obstruction, abdominal pain of obscure origin, impaired water-electrolyte metabolism, acute inflammatory diseases of the abdominal cavity, proctitis and hemorrhoids in the acute stage, strangulated hernia, bleeding from the gastrointestinal tract, uterine bleeding, 3 https://vitaforest.eu/en/cassia-wiki.html 10/1/21 cystitis, spastic colitis, spastic constipation, pregnancy, lactation, children under 12 years old.

  • Mothers, Markets and Medicine Hanna Lindh
    Mothers, markets and medicine The role of traditional herbal medicine in primary women and child health care in the Dar es Salaam region, Tanzania Hanna Lindh Degree project in biology, Bachelor of science, 2015 Examensarbete i biologi 15 hp till kandidatexamen, 2015 Biology Education Centre, Uppsala University Supervisors: Sarina Veldman and Hugo de Boer 1 Abstract Traditional medicine is still the most common primary healthcare used in Tanzania, especially among women. The ethnobotanical studies performed in Tanzania have not explored women’s traditional medicine, with the result that we do not know that much about it, including if women’s usage of medicinal plants create a threat against the medicinal flora’s biodiversity or not. Field studies consisting of interviews and collections of medicinal plants were carried out in the Dar es Salaam region in Tanzania before identifying the collected specimens by DNA barcoding, literature and morphology in Uppsala, Sweden. The 33 informants belonged to 15 different ethnic groups and 79% of them had migrated to Dar es Salaam. A total of 249 plant species were mentioned for women’s healthcare and 140 for children’s healthcare. The medicinal plants frequently reported as used for women’s health and childcare during structured interviews and free-listing exercises were Senna occidentalis/ Cassia abbreviata, Zanthoxylum sp., Clausena anisata, Acalypha ornata and Ximenia sp. The most salient uses of medicinal plants by women were during pregnancy, childbirth, menstruation, to induce abortion, and for cleansing infants and treating convulsions in children. Most of the fresh specimens were collected from disturbance vegetation. The informants having most interview answers in common were the market vendors, healers and herbalists and they were the only informants that mentioned species listed as vulnerable on the IUCN Red List of Threatened Species.

  • Characteristics of the Stem-Leaf Transitional Zone in Some Species of Caesalpinioideae (Leguminosae)
    Turk J Bot 31 (2007) 297-310 © TÜB‹TAK Research Article Characteristics of the Stem-Leaf Transitional Zone in Some Species of Caesalpinioideae (Leguminosae) Abdel Samai Moustafa SHAHEEN Botany Department, Aswan Faculty of Science, South Valley University - EGYPT Received: 14.02.2006 Accepted: 15.02.2007 Abstract: The vascular supply of the proximal, middle, and distal parts of the petiole were studied in 11 caesalpinioid species with the aim of documenting any changes in vascular anatomy that occurred within and between the petioles. The characters that proved to be taxonomically useful include vascular trace shape, pericyclic fibre forms, number of abaxial and adaxial vascular bundles, number and relative position of secondary vascular bundles, accessory vascular bundle status, the tendency of abaxial vascular bundles to divide, distribution of sclerenchyma, distribution of cluster crystals, and type of petiole trichomes. There is variation between studied species in the number of abaxial, adaxial, and secondary bundles, as seen in transection of the petiole. There are also differences between leaf trace structure of the proximal, middle, and distal regions of the petioles within each examined species. Senna italica Mill. and Bauhinia variegata L. show an abnormality in their leaf trace structure, having accessory bundles (concentric bundles) in the core of the trace. This study supports the moving of Ceratonia L. from the tribe Cassieae to the tribe Detarieae. Most of the characters give valuable taxonomic evidence reliable for delimiting the species investigated (especially between Cassia L. and Senna (Cav.) H.S.Irwin & Barneby) at the generic and specific levels, as well as their phylogenetic relationships.

This article is published with open access at Springerlink.com Abstract: Sudanese folk medicine represents a unique blend of indigenous cultures with Islamic, Arabic and African traditions. In addition, Sudan encompasses different terrains and climatic zones, ranging from desert and semi-desert in the north to equatorial with a short rainy season (semi-aridand semi-humid) in the centre to equatorial with a long rainy season (arid-humid and equatorial- humid) in the south. This variation contributes to the immense diversity of vegetation in the region. The flora of Sudan consists of 3137 species of flowering plants belonging to 170 families and 1280 genera. It is estimated that 15% of these plants are endemic to Sudan. The intersection of diverse cultures and the unique geography holds great potential for Sudanese herbal medicine. Medicinal and aromatic plants and their derivatives represent an integral part of life in Sudan.
