Buransh: The Himalayan states remain adorned with nature's breathtaking beauty throughout the year, but the arrival of spring brings a unique charm. During the months of January, February, March, and April, the hills come alive with a variety of seasonal flowers and fruits. Among them, the vibrant "Buransh" (Rhododendron arboreum) stands out, painting the landscapes with its deep red and pink hues.
What is Buransh (Rhododendron Arboreum)?
Buransh, also known as Rhododendron in English and "Kurvak" in Sanskrit, is the state tree of Uttarakhand and the state flower of Himachal Pradesh and Nagaland. The botanical name of Buransh is Rhododendron arboreum SM. The name "Rhododendron" originates from two Greek words: "Rhod" (meaning rose or pink-red) and "Dendron" (meaning tree), referring to its characteristic rosy blooms.
This evergreen tree is typically found at altitudes ranging from 1,500 to 3,600 meters and can grow up to 20 meters tall. Its rough, pinkish-brown bark and dense, lanceolate leaves make it a unique sight in the Himalayan forests. The flowers bloom in clusters and are known for their large, bell-shaped, deep red or pink petals.
Geographic Distribution of Buransh
Buransh is native to the Indian subcontinent and thrives in the Himalayan regions. It is also found in neighboring countries like Bhutan, China, Nepal, Pakistan, Thailand, and Sri Lanka.

Economic Significance of Buransh
Buransh has significant economic value due to its versatile applications:
- Timber and Fuel: The wood of the Buransh tree is used for making charcoal, tool handles, boxes, posts, and plywood.
- Traditional Food Uses: The petals of Buransh flowers are used in Uttarakhand’s traditional cuisine. They are commonly offered to deities in religious rituals.
- Air Purification: In Arunachal Pradesh, Buransh leaves are burned along with juniper and pine to purify the air.
Culinary and Medicinal Uses of Buransh
Buransh is widely consumed in various forms across the Himalayan regions:
- Buransh Juice (Squash): In Uttarakhand and Himachal Pradesh, Buransh juice is a popular beverage known for its cooling and refreshing properties. It has a distinct floral and citrusy taste and is widely consumed during summer.
- Pickles, Jams, and Chutneys: The locals prepare pickles, jams, and chutneys using Buransh petals, adding a tangy and slightly sweet flavor to their diet.
- Health Benefits: The flowers and bark of Buransh have been traditionally used in treating headaches, fever, digestive disorders, and respiratory issues. The soft leaves are applied to the forehead to relieve headaches.
Buransh and Covid-19: A Scientific Breakthrough
A recent study by the Indian Institute of Technology (IIT) Mandi and the International Centre for Genetic Engineering and Biotechnology (ICGEB) has revealed that Buransh petals contain phytochemicals with potential anti-Covid-19 properties. Researchers found that these phytochemicals prevent the coronavirus from replicating by binding with its key enzymes.
According to Dr. Ranjan Nanda of ICGEB, Buransh phytochemicals work in two ways:
- Inhibiting Virus Replication: The phytochemicals bind to an enzyme that helps the virus replicate itself.
- Blocking Entry into Human Cells: The compounds also interact with the ACE-2 enzyme in the human body, which the virus uses to enter cells.
This groundbreaking research suggests that Buransh could play a crucial role in developing future antiviral treatments.
Impact of Climate Change on Buransh
Climate change has started affecting the flowering patterns of Buransh. Rising global temperatures and erratic rainfall have led to early blooming, which disrupts the natural cycle of pollination and seed formation.
Typically, Buransh buds remain protected during the cold winter months and bloom when temperatures rise to 20-25°C. However, with unpredictable temperature fluctuations, the blooming cycle is often disturbed, affecting its survival. The IUCN Red List of Rhododendrons has highlighted the importance of conserving Buransh due to its role in maintaining soil stability and watershed protection in the Himalayas.
Buransh is not just a beautiful seasonal flower but also an integral part of the Himalayan ecosystem and culture. From its economic significance to its medicinal properties, this vibrant flower continues to be a valuable natural resource. However, the effects of climate change pose a serious threat to its existence. Conservation efforts and further scientific research can help preserve this remarkable tree for future generations.
