Saussurea is a genus of about 300 species of flowering plants in the tribe Cardueae within the family Asteraceae, native to cool temperate and arctic regions of East Asia, Europe, and North America, with the highest diversity in alpine habitats in the Himalayas and East Asia. Common names include saw-wort and snow lotus, the latter used for a number of high altitude species in East Asia.
They are perennial herbaceous plants, ranging in height from dwarf alpine species 5–10 cm tall, to tall thistle-like plants up to 3 m tall. The leaves are produced in a dense basal rosette, and then spirally up the flowering stem. The flowers form in a dense head of small capitula, often surrounded by dense white to purple woolly hairs; the individual florets are also white to purple. The wool is densest in the high altitude species, and aids in the thermoregulation of the flowers, minimising frost damage at night and also preventing ultraviolet light damage from the intense high-altitude sunlight.
De Candolle named the genus after Horace-Bénédict de Saussure (1740–1799) and Nicolas-Théodore de Saussure (1767–1845). [2]
A number of the high alpine Himalayan species are grown as ornamental plants for their decorative dense woolly flowerheads; they are among the most challenging plants to grow, being adapted to harsh climates from 3500 to 5000 m altitude, demanding cool temperatures, a very long (up to 8–10 months) winter rest period, and very good soil drainage in humus-rich gravel soils.
Costi amari radix or costus root was an important item of Roman trade with India, and is believed to have been the dried root of Saussurea lappa . [3]
Several varieties of snow lotus are used in traditional Tibetan medicine. Saussurea lappa is used a component of the traditional Tibetan medicine Padma 28. Research conducted on the Himalayan medicinal plants by C.P. Kala reveals that the practitioners of Tibetan medicine living in the Pin Valley of Himachal Pradesh use its root for curing dysentery and ulcer. [4] Saussurea laniceps , Saussurea involucrata and Saussurea medusa flowers and stems have long been used in traditional Chinese medicine for the treatment of rheumatoid arthritis, cough with cold, stomachache, dysmenorrhea, and altitude sickness, and has been found to have antiinflammatory and analgesic effects, [5] as well as cardiotonic, abortifacient, anticancer, [6] and antifatigue actions. [ citation needed ] Saussurea laniceps have been proven to be more effective than Saussurea involucrata and Saussurea medusa. [7]
Saussurea obvallata is one of the most sacred species in India, and has been used for offerings to goddess Nanda Devi for time immemorial. [8] [9]
Saussurea lappa and has been shown to inhibit the mRNA expression of iNOS by lipopolysaccharide stimulated macrophages, thus reducing nitric oxide production.[ citation needed ] In rats, high doses of 50-200 milligrams per kilogram of crude ethanolic extract reduced observed inflammation in standard laboratory tests, and 25-100 milligrams per kilogram of the sesquiterpene fraction of the extract reduced several molecular markers of inflammation. [10] [11] Ethanol extracts were shown to have analgesic and antiinflammatory effects at high doses of 75-300 milligrams per kilogram. As the slow-growing wild plant is endangered by collections, a substitute grown in tissue culture has been suggested, which is mostly equivalent. Generally the analgesic and antiinflammatory effects of the plant are much inferior to those of indometacin.
In most Chinese martial arts literature, the snow Lotus was classified a rare herb as precious as lingzhi mushroom, and old ginseng.
The Himalayas, or Himalaya is a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau. The range has some of the Earth's highest peaks, including the highest, Mount Everest. More than 100 peaks exceeding elevations of 7,200 m (23,600 ft) above sea level lie in the Himalayas.
The Karakoram is a mountain range in the Kashmir region spanning the border of Pakistan, China, and India, with the northwestern extremity of the range extending to Afghanistan and Tajikistan. Most of the Karakoram mountain range falls under the jurisdiction of Gilgit-Baltistan, which is controlled by Pakistan. Its highest peak, K2, is located in Gilgit-Baltistan, Pakistan. It begins in the Wakhan Corridor (Afghanistan) in the west, encompasses the majority of Gilgit-Baltistan, Pakistan and extends into Ladakh and Aksai Chin.
The Tibetan Plateau, also known as Qinghai–Tibet Plateau and Qing–Zang Plateau, is a vast elevated plateau located at the intersection of Central, South, and East Asia covering most of the Tibet Autonomous Region, most of Qinghai, western half of Sichuan, Southern Gansu provinces in Western China, southern Xinjiang, Bhutan, the Indian regions of Ladakh and Lahaul and Spiti as well as Gilgit-Baltistan in Pakistan, northwestern Nepal, eastern Tajikistan and southern Kyrgyzstan. It stretches approximately 1,000 kilometres (620 mi) north to south and 2,500 kilometres (1,600 mi) east to west. It is the world's highest and largest plateau above sea level, with an area of 2,500,000 square kilometres (970,000 sq mi). With an average elevation exceeding 4,500 metres (14,800 ft) and being surrounded by imposing mountain ranges that harbor the world's two highest summits, Mount Everest and K2, the Tibetan Plateau is often referred to as "the Roof of the World".
Valley of Flowers National Park is an Indian national park which was established in 1982. It is located in Chamoli in the state of Uttarakhand and is known for its meadows of endemic alpine flowers and the variety of flora. This richly diverse area is also home to rare and endangered animals, including the Asiatic black bear, snow leopard, musk deer, brown bear, red fox and blue sheep. Birds found in the park include Himalayan monal pheasant and other high-altitude birds.
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens. Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season.
Saussurea laniceps is a rare snow lotus found only in the Himalayas including southwest China. It might also occur in northern Burma. It grows above about 3,200 m (10,500 ft) altitude on alpine scree slopes. It is reputed to have medicinal properties according to traditional Chinese medicine. Among the snow lotus, Saussurea laniceps is proven to be more effective for its anti-inflammatory and anti-nociceptive effects.
