The gastrointestinal medicine Seirogan has been a household staple medicine used for over 100 years.
The main ingredient, Japanese Pharmacopoeia (JP) Wood Creosote, a crude drug, adjusts the water balance in the intestines without stopping normal intestinal movement and restores the stomach to a normal state. It is especially effective for soft stools and diarrhea caused by food poisoning, water poisoning, indigestion, and soft stools and diarrhea caused by stress or colds. This medicine is a soft pill containing moisture, formulated with crude drugs such as JP Wood Creosote, Asenyaku Powder, Phellodendron Powder, Licorice Powder, and Chenpi Powder.
A gift from the forest

Seirogan has a distinctive smell. Some say, "This smell seems effective!" while others find it a bit unpleasant. This is the smell of the main ingredient Japanese Pharmacopoeia (JP) Wood Creosote. This JP Wood Creosote is the main component that acts on the stomach in Seirogan.
When logs such as beech and pine are carbonized, the smoke produced is cooled, liquefied, and left to stand to obtain wood tar. JP Wood Creosote is obtained by repeatedly distilling and purifying this wood tar. As you can see from this process, JP Wood Creosote is a crude drug made only from natural substances.
Taiko Pharmaceutical's Seirogan and Seirogan Sugar-coated A use JP Wood Creosote, consistently manufactured and managed domestically from raw materials.
The slightly peculiar smell of Seirogan... this is also a sign of safety born from the forest.
