I just pick up neem capsules online or at local healthfood store. The cough I am talking about is one caused by mucus either draining down the throat or stuck around the tonsils and irritate the airway. I've not tried it for coughing spasms, just where there's mucus that refuses to drain, because it's become infected. In my last bout with the flu, or whatever the heck it was, I had a sore, aching throat and I knew I had mucus there. I had my tonsils yanked when I was 4, so I didn't have any lymph nodes there to fight the infection. I started on the neem and in about 6-8 hours, I was coughing up smallish globs of green mucus. I stopped taking the neem after a couple of days and I quickly realized I needed to go back on it because the mucus was turning green again. After about 4 days on the neem, the mucus was completely broken up and I was coughing up less and less mucus (clear).
