natrum sulphur and calc carb for all doctors only

My mom had skin itching problem but not cured after two years of allopathy and 7 months of homopathic
After it i search on internet and find
She had dry skin and red and swelling skin

So i gave her sulphur 200 2 times for 1 week but things are not cured and at high during night.

So i select silicea 30c in morning for dry skin and apis melifica 200 2 times day.but i think only silcea worked because no dry skin but itching still there.
So i cont. Only selicea 30c for one week.i read it works for many days so tell her to take it once in week.

So for itching i gave her psonricum 1m once in day and also eat once in day for two days for slow down itching.
After 2 days i gave her natrum sulphur 6x for approx 3 month because i think liver is main cause
AND THATS THE WONDER ITCHING JUST GONE.

which not happen in last 3 years. But i think still she have little bit she not saying because she not see such clean from years.
ONE MORE complian she have pain in sholders arms and back chest.
So i cheak her report ,when she use allopathy. And find she has weak bones due to less CALCIUM.

Now natrum sulphur 4 tab once in morning but i want to add CALC CARB with it but i want to know natrum have sulphur it is safe with CARB ? I find on internet that calc carb and sulphur should not given at same day. Any sugg..
