Although a good keyword, I think the weakness of this domain is that scurvy is no longer a very common disease. It's also not a popularly searched term in India.
I think if you were going to develop it, it could be quite a fun pirate based website (as pirates and seamen were often those most at risk of developing scurvy) but I find it hard to realise any high value.
You might be better off choosing a more 'popular' and 'current' disease if you wanted to target this niche (if you can call it that). For example Chlamydia.IN is not currently registered. This has much better stats than scurvy and is a current and very real concern. There are plenty of other modern day diseases that are yet to be regged too, like measles.IN, mumps.IN, tetanus.IN, thrush,IN etc (although I'm not 100% sure on how strong their search stats are)
All the best with whatever you choose to do.
