Please can you help

I have excess sweating of my head and face, it gets so bad that it drips off my hair and it is very embarrassing

I have read that Lecithin capsules and Sage tea can help with this problem am I correct and is Lecithin safe to take

I am a hairdresser and have a healthy diet and a fair amount of exercise I am 69 and over the change of life

Hope you can help me

Thank you
