MEDICINAL HERBS and FLOWERING PLANTS GARDEN in VIGNAN's CAMPUS Objectives: 1. to Grow and Maintain the Flowering and Medicinal
MEDICINAL HERBS AND FLOWERING PLANTS GARDEN IN VIGNAN’S CAMPUS Objectives : 1. To grow and maintain the flowering and medicinal important herbs in the vicinity of Hanuman Statue to bring elegance to the campus. 2. To design compost units and develop organic manure for the cultivation of herbs. 3. To prepare herbal decoction, syrup and infusions using roots, leaves, stem of propagated medicinal herbs both standalone and combinatorial mixtures. 4. To train students in the identification and taxonomy of medicinal herbs and extraction procedure, to screen secondary metabolites. Rationale: As our lifestyle is now getting techno-savvy, we are moving away from nature. However, we cannot escape from nature for we are part of nature. Natural herbal flora withstood the vagaries of climatic changes through the ages of earth. In addition, they are endowed with safe compounds preferably positive health benefits and hence they are comparatively safer and eco- friendly. Traditionally there lots of herbs are in use to relieve humans and livestock from the ailments. Therefore, there is a need to promote them to save human lives. These herbal products are today are the symbol of safety in contrast to the synthetic drugs, that are regarded as unsafe to human beings and environment. Although herbs had been priced for their medicinal, flavoring and aromatic qualities for centuries, the synthetic products of the modern age surpassed their importance, for a while. It is primarily because of the marketing strategies adopted to promote synthetic products. It’s time to promote and propagate the various species of medicinal plants globally particularly among students and woman folk to appraise their value in healthcare. -
Towards Resolving Lamiales Relationships
Schäferhoff et al. BMC Evolutionary Biology 2010, 10:352 http://www.biomedcentral.com/1471-2148/10/352 RESEARCH ARTICLE Open Access Towards resolving Lamiales relationships: insights from rapidly evolving chloroplast sequences Bastian Schäferhoff1*, Andreas Fleischmann2, Eberhard Fischer3, Dirk C Albach4, Thomas Borsch5, Günther Heubl2, Kai F Müller1 Abstract Background: In the large angiosperm order Lamiales, a diverse array of highly specialized life strategies such as carnivory, parasitism, epiphytism, and desiccation tolerance occur, and some lineages possess drastically accelerated DNA substitutional rates or miniaturized genomes. However, understanding the evolution of these phenomena in the order, and clarifying borders of and relationships among lamialean families, has been hindered by largely unresolved trees in the past. Results: Our analysis of the rapidly evolving trnK/matK, trnL-F and rps16 chloroplast regions enabled us to infer more precise phylogenetic hypotheses for the Lamiales. Relationships among the nine first-branching families in the Lamiales tree are now resolved with very strong support. Subsequent to Plocospermataceae, a clade consisting of Carlemanniaceae plus Oleaceae branches, followed by Tetrachondraceae and a newly inferred clade composed of Gesneriaceae plus Calceolariaceae, which is also supported by morphological characters. Plantaginaceae (incl. Gratioleae) and Scrophulariaceae are well separated in the backbone grade; Lamiaceae and Verbenaceae appear in distant clades, while the recently described Linderniaceae are confirmed to be monophyletic and in an isolated position. Conclusions: Confidence about deep nodes of the Lamiales tree is an important step towards understanding the evolutionary diversification of a major clade of flowering plants. The degree of resolution obtained here now provides a first opportunity to discuss the evolution of morphological and biochemical traits in Lamiales. -

The use of these seeds is unsafe. They can cause hallucinogenic effects, nausea, vomiting, elevated heart rate, elevated blood pressure, (severe) fatigue and lethargy. These health effects can occur even when the seeds are consumed at the recommended dose. This is the conclusion of a risk assessment performed by RIVM. Hawaiian Baby Woodrose seeds are sold as raw seeds or in capsules. The raw seeds can be eaten as such, or after being crushed and dissolved in liquid (generally hot water). -

BLEEDING HEART VINE-VARIGATED Clerodendrum X Thompsoniae ‘Variegata’
BLEEDING HEART VINE-VARIGATED Clerodendrum X Thompsoniae ‘Variegata’ Characteristics • Vine • Sun: Part shade • Zone: 10 to 12 • Water: Medium • Height: 12.00 to 15.00 feet • Maintenance: Medium • Spread: 12.00 to 15.00 feet • Suggested Use: Annual • Bloom Time: Seasonal bloomer • Flower: Showy • Bloom Description: White calyces with • Leaf: Evergreen dark red corolla Culture Use a trellis to train this vine in the house. To grow glory-bower or bleeding heart vine indoors, a winter rest is required. This can be accomplished by moving the vine to a cooler location away from any heat source. A spot between 60 to 65F during the day and 5 to 10 degrees lower at night would be ideal. Some leaf drop is a normal response to entering winter dormancy. During this period, water just enough to keep the soil from drying out and withhold fertilizer. In late winter or early spring, prune the vine before new growth emerges. Because flower buds are produced on current season’s growth, pruning at this time will encourage the production of vigorous flowering shoots. Do not be afraid to prune severely. Thin out old, overcrowded shoots and any other far-reaching growth to keep the vine in bounds. After pruning, move the plant to a warm, brightly lit location or outdoors if temperatures have warmed sufficiently. Water when the soil surface feels dry. Noteworthy Characteristics Clerodendrum thomsoniae, commonly called bleeding heart vine, is a twining evergreen shrub or vine. It usually blooms during the warm months and provides showy white flowers with dark red corollas giving a striking contrast. -

Ipomeas Background the Genus Ipomoea Consists of Around 500
Ipomeas Background The genus Ipomoea consists of around 500 species of twining vine, bushes or trees from the Convolvulaceae family. Some studies (D. Austin, 1997) have listed between 600 and 700 species, of which over half originate from North and South America. • First there is the Ipomoea purpurea, very well suited to for the temperate climate: it is an American climbing plant whose blue-purple aspect is widely known and which the Americans call Gandpa Ott. The pink flower is also known in Europe. • The ipomoea tricolor (ipomoea tricolor or morning glory) originates from Mexico and Central America. In that region the flower is known as badoh negro and its seeds have been used as hallucinogenics since the Aztec era. It is grown the entire year and puts out a good number of blue flowers – really blue! – of around 10-15 cm. Their highlight is a yellow center. • The ipomoea nil came from Japan some 1,000 years ago from China. At the time it was used as a diuretic; the Chinese had obtained it from the Arabs who traded with all the small kingdoms of East Africa. The Nil arrived accompanied by other Ipomoeas, including one from the Himalayas and another from the Beijing area. They quickly appeared in gardens and were crossed with each other to obtain different colors. They went from being bluish, to pink then white, and are known in Europe as “ipomoea purpurea” and tricolors. One that is much less so is the Japanese ipomoea, “ipomoea nil” or “Asagao”. These flowers found their way into Japanese poetry because they represent a strong theme in Japanese culture: life is short, as is beauty.
