There are probably as many causes of coughs as there are cough sufferers.
A good cough remedy should have a strong match to your unique cough symptoms.
Then the cough will disappear.
This is how homeopathy works.
By matching the symptoms of the cough remedy to your symptoms.
The stronger the match, the better the result will be.
One of the most unpleasant coughs is a paroxysmal cough.
One when the coughing comes in spells or spasms.
It's hard to catch your breath between the spasms.
So you may go blue.
The severity of the cough may cause a blood nose.
And the coughing can be so bad when you lie down, or in the early hours of the morning, that you scarcely get any sleep.
Probably the rest of the household won't either, so you'll be highly popular.
If this symptom picture sounds anything like your cough, then this homeopathic remedy is likely to resolve it, and return your popularity.
It's called Drosera and the strong keynotes for it are:

• violent, spasms of coughing which come so close together you can't get your breath in between, so become cyanotic (blue)
• the severity of the cough causes a blood nose
• cough is worse at night, especially after midnight

And the more minor keynotes of this remedy are:

• worse after eating
• worse lying down
• very painful chest - you clutch at it
• often vomiting accompanies the cough

The violence of this cough resembles whooping cough, Homeopaths don't use disease labels.
Instead we use your unique symptoms.
So whether or not you have been diagnosed with whooping cough, if your symptoms look like those of Drosera, then this will be an excellent cough remedy for you.
