welcome to healthcaremagic
sorry to say there is low chance of gaining height for you. Normally height gain age range from 14-21yrs. But beyond this less change. Also height is hereditary..if you had history of low height in your generations.There is no specific description of height gain medicine in Ayurveda but the calcium suppliment may be helpful. yoga
, exercise and some asanas are effective. Please dont follow any advertisement for height gain medicines. There are useless except loss of money.
