Sustainable Impact: the Natural Fiber, Allo [Himalayan Nettle]

Posted on April 29 2016

Do you know where, how and who makes the products that you purchase?  Most of the companies don’t consider this information is necessary, yet some tries to hide it and while some don’t know themselves!  On contrary, knowing that the product you use comes from sustainable resources meeting environmental standards and paying fairly to makers is special, and that adds boundless worth to the product.  

Kolpa believes - as a consumer, you have the right to ask.  At Kolpa, we LOVE sharing the stories of products and its producers.  Today, we bring you the story of the “future fiber” - known as Allo, the Himalayan Nettle.


Allo [in Nepali] is commonly known as the “Himalayan Wild Nettle” [Girardina diversifolia]The plant is native to seven Asian countries (Bhutan, China, India, Myanmar, Malaysia, Nepal and Srilanka). In Nepal, Allo is found in the high mountains and historically consumed by indigenous people such as Rai, Sherpa, Magar, Chhetri, and Gurung. Allo’s fiber and fabric are all natural, fully biodegradable and robust.  Currently, the use of Allo has gained popularity beyond its native users.

Allo, the plant

Allo grows up to 1.5 to 3 meters tall with perennial rootstocks in the wild between 1,500 to 3,000 meters altitudes.  During April plant starts to grow.  When it matures it reaches up to 3 meters which is when it contains the best fibers of unique quality.

Allo fiber processing in Nepal

Allo stem is harvested using hands and simple tools.  The outer bark is stripped off using teeth.  This is a traditional method used by communities for generations.  Once completely peeled, they are tied in bundles to sun-dry.  The harvesting occurs in December, which is a perfect time to get quality fiber.

Once dried, the bark is soaked [in water] overnight. The overnight soaked bark is boiled for 3 to 4 hours with wood ashes, which is traditionally done at evening.  The boiling bark is left to simmer overnight in the fire. The ashes acts as alkali that helps to break the bonds of fibers. In the morning the bark is washed thoroughly in the running water while constantly beating it.  Mostly, this is done on the river bank.  The running water in the river clears any impurities.  Washing and beating is repeated for 2 to 3 times.  Then the processed fiber is mixed with special clay [called kamero maato] and dried in the sun for a few days. Once the fiber is dried, the clay is removed by beating with stick and rubbing with hands.  This traditional method to extract Allo fiber is still in practice in Nepal.
