Hi thanks for posting your query.As you have mentioned that your mother is suffering from headache which is relieved after taking pain killerdrug.I want to know is the pain mild or severe and what is the frequency of pain. There are many causes for headaches.One of the cause is faulty diet and lifestyle which is causing ama formation in manovahi strotras.Few effective remedies are Consume food which is cooling in nature like aloe vera ,am LA,mint,coriander,cucumber ,coconut water. Avoid pitta aggravating diet like tea,caffeine,alcohol,spices,non veg. I will highly recommend therapies like NASYA( administration of Anu oil into both nostrils) SHIRODHARA( pouring of medicated oil into forehead) Head massage with brahmi ,bhringraj oil Practise pranayam like anulom vilom,bhastrika,bhramri,udgeeth,meditation,shavasan,yoga nidra regularly. Boost your metabolism by going for a walk daily. Avoid exposure to sun. Herbal preparations useful for this purpose Sutshekhar ras, praval pisti,mukta pishti,pathyadi kwath Hope this answer is useful to you Best wishes for good health! Regards Dr.Pallavi
