बैज्ञानिक नाम: Parmelia nepalensis Tayl

परिवार: Parmeliaceae

परिचय

झ्याउ, जसलाई अंग्रेजीमा Lichen भनिन्छ, प्रायः चट्टानहरू र रूखहरूको छालामा पाइने एक प्रकारको जीव

हो। यो ढुसी र लेउको सहजीव रहेको संरचना हो। झ्याउलाई विशेषगरी उसले बाँच्नका लागि आवश्यक हावा र नमी मिल्ने वातावरणमा बढ्न मन पराउँछ। नेपालमा झ्याउको प्रमुख प्रजाति Parmelia nepalensis हो, जसले स्थानीय वातावरणसँग अनुकूलन गरिसकेको छ।

उपलब्धता

झ्याउ नेपालका विभिन्न भागहरूमा पाइन्छ, विशेषगरी १००० देखि ३००० मीटर उचाईमा। यो प्रायः घना वनमा र प्रदूषण रहित स्थानहरूमा बाँच्न सक्दछ। मध्य पश्चिम र सुदूर पश्चिमका पहाडी जिल्लाहरूमा यसको धेरै मात्रामा उपलब्धता छ। झ्याउको बृद्धि दर धेरै कम छ, जसले गर्दा यसको संरक्षण र उपयोगमा ध्यान दिनु आवश्यक छ।

सङ्कलन समय र व्यापारमा आउने भाग

झ्याउलाई वर्षभरि सङ्कलन गर्न सकिन्छ। व्यापारमा यसका सबै भागहरू प्रयोगमा ल्याइन्छ। झ्याउको सुकेको भाग अत्यन्त हलुका हुन्छ र यसको रंग सामान्यतया हरियो खैरो हुन्छ, जबकि तल्लो भाग हल्का सेतो रंगको हुन्छ।

प्रयोग र गुणहरू

झ्याउको उपयोग औषधीय क्षेत्र र अन्य उद्योगहरूमा महत्त्वपूर्ण छ। झ्याउको सार (extract) मानिसको स्वास्थ्यमा ठूलो योगदान पुर्याउन सक्छ। यसको विशेष प्रयोगहरूमा निम्नलिखित छन्:

1. औषधीय प्रयोग: झ्याउको सार विषाक्त खाद्य वस्तुहरूबाट हुने अस्वस्थता र महिनावारीको गडबडीमा प्रयोग गरिन्छ।

2. रङ निकाल्ने: झ्याउबाट प्राकृतिक रङ निकालिन्छ, जसलाई कपडा र अन्य सामग्रीमा प्रयोग गर्न सकिन्छ।

3. वातावरणीय सूचक: झ्याउलाई जैविक सूचकको रूपमा पनि प्रयोग गरिन्छ जसले वायु प्रदूषणको स्तर थाहा पाउन मद्दत गर्दछ। जब वातावरणमा प्रदूषण बढ्छ, झ्याउको वृद्धि दर र गुणस्तरमा कमी आउँछ।

संरक्षणको अवस्थाः

नेपाल सरकारले झ्याउलाई प्रशोधन नगरी निर्यातमा प्रतिबन्ध लगाएको छ। यसको संरक्षण र दिगोपनमा ध्यान दिन आवश्यक छ, ताकि भविष्यमा यसका लाभहरू प्राप्त गर्न सकियोस।

Introduction

Lichen, called झ्याउ in Nepali, is a unique, non-vascular plant that grows on rocks and tree bark. Lichen is a symbiotic association of an alga and a fungus; this helps them survive in a wide range of ecological conditions. One of the most common species found in Nepal is Parmelia nepalensis, which has adapted well to local conditions.

Availability

Lichens are distributed throughout Nepal, particularly between 1,000 to 3,000 meters of altitude. They prefer thick forests without pollution. The largest concentrations are found in the hilly districts of mid and far western Nepal. Lichens are very slow-growing, and as such, their conservation is very important.

Harvesting Time and Parts Used in Trade

Lichens can be collected any time of the year. The whole plant is used for trade. When dried, lichens are extremely light. The upper part is usually green-brown in color, and the lower part is a bit whiter.

Uses and Properties

Lichens have quite a number of medicinal uses and other industrial applications. Some of their most important uses include:

Medicinal Use: The extracts of lichens are good in the treatment of food poisoning and menstrual periodicity disturbance.

Lichen is also used in the extraction of natural dye, which is further applied in various textiles and fabrics.

Environmental Indicator: These lichens are the biological indicators of air quality. The increase in the rate of pollution decreases the growth and quality of lichens, and hence they show the signs of environmental problems.

Conservation Status

The Government of Nepal has banned the exportation of lichen without processing. This is in a bid to ensure sustainability and conservation so that the benefit of lichen be kept for generations yet unborn.

Conclusion

The role of lichen is very important, both in the ecosystem and economy of Nepal. It possesses some specific properties and medicinal benefits, which make it one of the key herbs in Nepal. Understanding the importance of the same will develop a sense of understanding towards the conservation of these types of value resources. Focus on herbs in Nepal not only pins the rich biodiversity of the country but also encourages people to progress in such a manner so that it enables sustainability for upcoming generations.

This survey of झ्याउ lays immense emphasis on its medicinal properties and ecological importance, proclaiming loudly that these tiny organisms, lichens, too, can play a very important role in human life and the environment.
