If yes , please do reply as soon as possible ________
Please tell a safe method

Sorry but unless you look at MAJOR surgery then there is no realistic way outside of genetics and simply growing as you age.

Shouls I use homopathic medicine

You can hire a witch doctor and let them kill chickens to bless the "height" god, it will not make you taller, homeopathic medicine is great I believe in it fully. It will not make you higher, there is no way to get higher from pills, creams or gimmicky items

Can playing basketball increase my height after 18

No, there is NO WAY

NO NO NO Way

There is nothing to increase height, at 16 you will grow a little over the next couple years but there is nothing that will change it.
