The valley has an unusually rich flora of over 600 species with many rarities. Animals found are nationally rare or endangered. 13 species of mammals are recorded for the Park and its vicinity although only 9 species have been sighted directly. Other factors that are contributing to ecotourism are beautiful landscapes, peaks, lakes and tarns etc. But now-a-days the problem of Solid waste is increasing at an alarming rate because of the heavy influx of tourists and improper management practices.

Plants of the genus Aconitum L (family of Ranunculaceae) are known to be among the most toxic plants of the Northern Hemisphere and are widespread across Europe, Northern Asia and North America.

The present study was aimed to identify and document the ethnoveterinaryplants used by tribal migratory shepherds in high hills of Chitkul range in Kinnaur district of Himachal Pradesh located in western Himalayas. In high hills of Chitkul range a total of 33 ethnoveterinary plants (herbs 11, shrubs 6, trees 4, climber 1 and grasses 11) were used by shepherds. The commonly used plant species were Abies spectabilis, Asparagus filcinus, Aconitum heterophyllum, Betula utilis, Cannabis sativa, Ephedra gerardiana, Rhododendron anthopogon, Thymus serphyllum and Trillium govanianum etc. It was found that more scientific studies should be carried out to determine the effectiveness of identified plant species used in primary healthcare of livestock by tribal migratory shepherds.

Summary An assessment of safety considerations with respect to human usage of complementary medicine preparations made from the substance Aconite (any part of the plant Aconitum napella, otherwise known as Monkshood), has been undertaken. The available toxicological data was reviewed, and levels of intake of the known toxic constituents, the alkaloids aconitine, mesaconitine and jesaconitine, known to be associated with adverse effects and possible fatality in humans, were determined. From this assessment, concentration levels of the known toxic alkaloids below which no toxic effects would normally be associated with their internal ingestion or use, was determined. Levels of ingestion of these toxic components which could normally be deemed as completely safe, were then ascertained. This assessment was then applied to an evaluation of homoeopathic Aconite-containing preparations available in the marketplace, to select ‘cut off points’ below which general sales classification is deemed appropriate. These calculations were based upon both concentration levels of the toxic alkaloids, as well as the maximum recommended pack size of preparations containing them. Aconite: an introduction Aconite (a preparation made from either the roots or herb of the European shrub Aconitum napellus, or other Aconitum species ), has long been used both as a traditional herbal medicine as well as a homoeopathic remedy.

POISONOUS HEMLOCKS THEIR IDENTIFI CA TION AND CONTROL THE poisonous plants referred to in this publica­ tion as "hemlocks" are members of the carrot or parsley family, Umbelliferae, and should not be confused with true hemlocks, which are coniferous trees of the pine family, Pinaceae. Poisonous hem­ locks are of two genera: Conium (Poison Hemlock), and Cicuta {Water Hemlock). They have a general family resemblance to one another but are not closely related; their toxic properties and effects are different, they present different problems to the live­ stock industry, and they have different diagnostic features.
