What is the best cure when you have a hard and dry cough?

Vit. C and lots a lots of water..especially if she drinks too much coffee..and also gargle..if your mom wants to take medicine, then start with carbocistine to soften the dry cough. But if the cough will not be cured, please go to a doctor..

i have a special treatment for cough.get a red palmoil ,add sugar to it and take it 5 times a day. or take ginger and honey together

ya that's nice besides taking food like this. please go for minor meditation . pranayama is the very best medicine for this type of colds. u can get curified ion just 2 days

Most coughs start from the allergies. You have to see what your's mom is allergetic to and then avoid that. You can try gargling with some salt and pure ghee in it. best of luck 'n have a nice day, bye

i think your mom need to drink hot milk with honey not coffee! Its the best cure for cough! I took it last year, i got 2 months hard cough, and it was gone after 2 weeks of drinking milk with honey and i am very healthy now,i always drink a glass of it before i go to sleep, its a very good food supplement and remedy for many sickness! she should use raw honey because it has a lot of nutrients, like antibacterial and vitamins! Vitamins C is also good for her health! Hope your mom will get well soon!
