Hello,
Are you asking about somebody else? What her age? Is she married, if yes, since when? How is her sexual life?
What kind of menstrual irregularity is there?
Has she undergone any investigations? Share all the reports with me.
Without knowing all these can't give you any medication.
Ask her to take more of green vegetables, nuts, salads, seasonal fruits, yellow coloured veggies, milk & milk products, plenty of water and enough of sleep & rest.
And homoeopathic medication ? Schwabe's Five Phos. And Alfaalfa Tonic ? both thrice daily for 1 month.
There after revert me back..take care.
