The blossoming of love for Semal
The beautiful scarlet flowers of Semal tree (Bombax ceiba L.) used to attract me when I was pursuing my Post Graduate from Mohanlal Sukhadia University, Udaipur, as it was planted in the botanical garden and was visible from the botany laboratory. However, I never knew that it is going to be a family member in my life until it was selected for my Ph.D. work by my supervisor. The journey, once embarked upon, led me to have such a intimate connection with Semal tree that I used to look for it in every piece of literature I came across.
Description of tree
Semal is a huge tree reaching heights of more than 40 m; having a stem armed with sharply pointed thorns and the pentafoliate leaves which fall during December-April. This leafless period is the commencement of large size, red colored flowers, thereby creating a magnificent appearance so as to call it as ’The King of the Forest Tree’. Therefore, spring is the season when true beauty of Semal tree unveils. Fruiting starts in April-May and black colored seeds enveloped in silky cotton, spreads through air after dehiscence of capsules. The excellent drought tolerance capacity and reclamation ability for waste lands make it an ideal choice for planting even along the roadsides. Interestingly, Semal tree has several names in Sanskrit language and the etymological analysis depicts each name reflecting a particular property of the plant (Jain and Verma, 2012).

Cultural versatility
Finding such a versatile tree is indeed a rare gift of nature. It has played an important role in human life as not only providing food (young buds as vegetable), fooder (leaves and flowers), fibre, fuelwood and medicine but an exemplary component of various cultural traditions including folk tales, folk songs, games, proverbs, epics etc. However, one of the disappointing tradition which led my attention towards its conservation was burning of this tree in thousands in Udaipur, Rajasthan during Holika-dahan festival which is celeberated every year on full moon day of Falgun (a month in the Hindu calendar). The tree is considered as ’Prahlad’-the mythological character which remained alive when his aunt ’Holika’ attempted to kill him by fire. The non-flammable quality of Semal tree is due to its thorny nature but this fact is forgotten and the debarked Semal stems are still sold in the market for burning as a traditional Holi-pole leading towards reduction in its population. Considering this, ’Semal Conservation Mission’ was intitiated under the aegis of Society for Microvita Research and Integreated Medicine (SMRIM), Udaipur which included awareness creation, massive planting and adopting an iron-pole as an alternate for burning Holi.
The Medicinal Semal Tree Sanctuary
Apart from this, it is also apt to call this tree as a ’Sanctuary’ or ’Birds’ paradise’. I personally observed several birds and animals enjoying on this tree whether using it for food, shelter, perching, roosting or nesting purposes. Moreover, it was amazing to see more than 15 bee hives on a single Semal tree in Kewra-ki-naal area, near Udaipur, thus validating its status as an ’Umbrella tree’. Another notable observation was an indigenous innovation of using wood of this tree for preparing an artificial limb by a tribal man living in Kotra, Udaipur.

Medicinally, every part of the tree is valuable whether it is thorn, gum, stem bark, root bark, root, flower, fruit, seed, silk-cotton or leaf and ethnic communities are utillizing its benefits since time immemorial. The codified systems of medicine, such as Ayurveda, Unani, Siddha and Chinese medicine also mentions use of this tree for treatment of several ailments. I too found favorable outcomes and reported anabolic, antioxidant, anti-hyperglycemic, hypolipidemic and fibrinolysis enhancing properties of its roots through scientific investigations.
Overall, the tree once selected for the scientific assessment of medicinal virtues became an integral part of my life and the bond thus formed remains alive to this day. Even till today, wherever I go and got a sight of Semal tree, my heart overflows with joy. Its magic reveals itself to anyone who learns to recognize this tree and embrace it with an open-heart.
