01 Do you ever feel like this?
✔️ Look in the mirror in the morning
Your face is swollen like a steamed bun, your double eyelids disappear, and even your rings feel tighter.
✔️ Had drinks last night
You wake up hungover, nauseous, dizzy, and feel completely drained.
✔️ Stayed in an air-conditioned room for too long
You start having diarrhea, your hands and feet are cold, you gain weight just by drinking water, yet you pee very little.
If any of these sound familiar, this post is a must-save for you.

Official indications (in simple words):

? Hangovers
Nausea, vomiting, dizziness, headache – helps detox alcohol and drains excess water fast.
? Acute gastroenteritis
Diarrhea, nausea, stomach rumbling – stops unprocessed water retention in the gut.
? Heatstroke, summer fatigue, motion sickness, early-stage diabetic thirst
Discomforts caused by disturbed water metabolism.

For any symptoms with “internal dampness + thirst and reduced urination,” Goreisan can help.
