This syrup has coated my throat and significantly reduced soreness since 1988. It’s particularly useful before bed, helping stop coughing for a good night's sleep. It's alcohol-free and lasts a long time, making it economical. Just remember to use the provided push-in cap to avoid issues later.

Most Useful Review
AMAZING! This stuff is simply incredible! We use it for various ailments, from smokers cough to cold and flu. I dislike getting sick, but that tickling cough that lingers for weeks is worse. This remedy knocks it out in days, not weeks. As an added bonus, it noticeably clears and brightens the skin.

Unbelievable! As a diabetic with low immunity, I frequently suffer from the flu and sinus issues. I stumbled upon Pei Pa Koa while searching for a remedy since I was too unwell to visit the pharmacy. I thought I’d give it a go, and this "elixir" works like magic. Its effect is truly remarkable! I will order more!

I've been using this cough syrup since 1988. Taken straight from the bottle, it coats my throat longer than others and significantly alleviates the itchiness and pain from a sore throat. It’s particularly helpful before bed, allowing me to sleep better without coughing.

A product that really works! I had a persistent tickle in my throat for over a year. I first purchased this in a health store and found the ingredients appealing. After taking two tablespoons, the tickle disappeared immediately, and I haven’t coughed since. I even bought more online, and I love mixing it with hot water and lemon. Children would enjoy this too, especially for asthma cases.
