Higher incidences of adverse reaction associated with the prolonged use of synthetic drugs has once again increased the faith of humans in the traditional systems of medicine and motivated them to return back towards the clinical proven remedies for the treatment. It is also true that number of modern medications used in the present scenario, were developed from various plants. In Unani System of medicine, numerous herbal drugs are mentioned for medicinal purpose. Siras (Albizia lebbeck (L.) Benth.) is one of them. It is found all over India. Almost all parts of this plant are used for the treatment of ailments such as migraine, conjunctivitis, diarrhea, jaundice, skin problems, asthma etc. Many chemical constituents have been isolated from Albizia lebbeck such as lebbekannin, echinocystic acid, flavonoids, Linoleic acid, saponins etc. This review highlights the medicinal properties and therapeutic uses of Albizia lebbeck and scientific studies conducted on the drug in human and animal models that will provide the further research direction.

A study was conducted to determine the phytotoxic effect of mercury on seed germination and seedling growth of an important arid legume tree Albizia lebbeck. The seeds germination and seedling growth performance of A. lebbeck responded differently to mercuric chloride treatment (1 mM, 3 mM, 5 mM and 7 mM) as compared to control. Seed germination of A. lebbeck was significantly (p < 0.05) affected by mercury treatment at 1 mM. Root growth of A. lebbeck was not significantly affected by mercury treatment at 1 mM, and 3 mM. Shoot and root length of A. lebbeck were significantly (p < 0.05) affected by 5 mM concentration of mercury treatment. Increase in concentration of mercury treatment at 5 mM and 7 mM significantly (p < 0.05) reduced seedling dry weight of A. lebbeck. The treatment of mercury at 1 mM decreased high percentage of seed germination (22%), seedling length (10%), root length (21.85%) and seedling dry weight (9%). Highest decrease in seed germination (51%), seedling (34%), root length (48%) and seedling dry weight (41%) of A. lebbeck occurred at 7 mM mercury treatment. A. lebbeck showed high percentage of tolerance (78.14%) to mercury at 1 mM. However, 7 mM concentration of mercury produced lowest percentage of tolerance (51.65%) in A. lebbeck. The seed germination potential and seedling vigor index (SVI) clearly decreased with the higher level of mercury. Plantation of A. lebbeck in mercury-polluted area will help in reducing the burden of mercury pollution. A. lebbeck can serve better in coordinating in land management programs in metal contaminated areas. The identification of the toxic concentration of metals and tolerance indices of A. lebbeck would also be helpful for the establishment of air quality standard.

Three tropical legumes, very different in growth form, but believed to be of potential value for animal production were evaluated by substituting the leaf meal made from each for lucerne at the level used in a standard diet for growing rabbits (50%). Each leaf meal had a nitrogen content of close to 3.5% and contributed about 60% of the crude protein in the diet. Albizia lebbeck and Clitoria ternatea showed no evidence of toxic or antinutrient effects. The protein digestibility of the complete diets were 66 and 61% respectively, implying a protein digestibility of the leaf of at least 50%. Both species would be suitable for practical production diets for rabbits and should be excellent for ruminants. In contrast, the diet containing Desmanthus virgatus had a protein digestibility of only 40%, implying that only about 15% of the leaf protein was available. The leaves showed marked non-enzymic browning on drying. When dried this species is clearly unsuitable as a feed for rabbits and possibly also for ruminants. However, it may well be valuable as fresh forage.

This study aimed to assess the effects of tree manures in comparison with NPK fertilizer on growth of Acacia senegal seedlings. It was conducted in the nursery of the Faculty of Forestry, University of Khartoum, Shambat (Lat.: $15^{\circ}$ 39' 387" N and Long.: $32^{\circ}$ 30' 871" E), during August 2008 and January 2009. The growing media were prepared by mixing ground foliage of trees with sandy soil (weight/volume) as follows, Albizia lebbeck (AL): 25 g, 50 g and 75 g; Azadirachta indica (AZ): 25 g, 50 g and 75 g; Khaya senegalensis (KH): 25 g, 50 g and 75 g; NPK fertilizer: 30 g per seedling. Albizia lebbeck and Azadirachta indica manures and NPK fertilizer have stimulated the Acacia senegal seed germination percentage in comparison with the control, with respective values of 89, 82.7, 81 and 71%. Khaya senegalensis manure has suppressed the Acacia senegal seed germination percentage with a value of only 49%. Effects of treatments on the seedlings growth parameters varied in the following percentages, in comparison to the control, shoot height: AZ 62.9%, AL 46%, KH 9.9% and NPK 27.8%; root length: AZ 25.8%, AL 31.5%, KH 30.6% and NPK 4.4%; diameter: AZ 75.2%, AL 37.1%, KH 34.3% and NPK 20%; Shoot biomass: AZ 319%, AL 195.2%, KH 57.1% and NPK 42.9%; root biomass: AZ 288.9%, AL 116.7%, KH 55.6% and NPK 16.7%%;. Thus, the effectiveness of the used substrates on the growth performance of Acacia senegal seedlings occurred in the following descending order: Azadirachta indica> Albizia lebbeck>Khaya senegalensis>NPK fertilizer. These results assert clearly the ameliorative and fertilizing characteristics of tree manures that can be reliably used for raising seedlings stocks in the nurseries.

Status of Arbuscular Mycorrhizal (AM) colonization in seven tree species (Albizia saman, Acacia auriculiformis A. Cunn. ex Benth., Albizia lebbeck, Chickrassia tabularis A. Juss., Eucalyptus camaldulensis Dehnn., Gmelina arborea (Roxb) DC, Swietenia macrophylla King.) collected from the hilly areas of Chittagong University (CU) was investigated. Roots and rhizosphere soil samples were collected in different seasons (pre-monsoon, monsoon and post monsoon). Percentage of AM colonization in root and number of spores/100 gm dry soil were assessed. The result of the investigation reveals that the intensity and percentage of AM colonization varied in different forest tree species in different seasons. In this study, maximum AM colonization and spore population were found in pre-monsoon and minimum were in monsoon season. The intensity of colonization was maximum in C. tabularis (74.43%) in pre-monsoon, A. lebbeck (69.45%) in monsoon and S. macrophylla (67.8%) in post monsoon seasons and minimum in A. auriculiformis (53.75%) during pre-monsoon, A. saman (24.4%) in monsoon and A. saman (19.36%) in post monsoon. The number of spores found per 100 g dry soil ranged between 164-376 during pre-monsoon, 27-310 during monsoon and 194-299 in post monsoon season. Out of six recognized genera of AM fungi, Glomus, Sclerocystis, Entrophospora, Scutellospora, Acaulospora and other unidentified spores were observed.

An experiment was set to understand the seedlings growth and nodulation capabilities of five potentially important leguminous agroforestry tree species of Bangladesh in response to application of organic fertilizer. Study was carried out in nursery bed on the seedlings of Acacia mangium Willd., Acacia hybrid, Acacia auriculiformis A. Cunn. ex Benth, Albizia lebbeck (L.) Benth. and Leucaena leucocephala (Lam.) de Wit. after sowing their seeds in polybags filled with different medium. Farmyard manure or decomposed cow dung was applied as the source of organic fertilizer with other potting media. The growth and nodulation performance of seedlings of the selected species were measured three moths after the first seed was emerged. The different soil: organic manure ratios' used during the experiment were, 1:1, 2:1 and 3:1. The effects of organic fertilizer on growth and nodulation were compared to that of seedlings grown in control. The results revealed a positive correlation between seedling growth and the different doses of organic fertilization (i.e. seedling growth was enhanced significantly with different treatments containing higher proportion of organic fertilizer). In few cases a negative effect was observed after applying higher levels of organic manure. It was also apparent that the nodulation in terms of nodule number and size was inhibited significantly by the application of organic fertilizer.
