Hello. I am a mother caring for a high school senior. My child is turning 100 days old soon, and during the vacation, he definitely seems lethargic and irritable, so I’m not sure what I should do for him. As the CSAT approaches and the workload increases, I’m worried that this might be a critical moment. Coming home late studying has always been the case since the beginning of this year, so there is nothing I can do about it. However, perhaps due to the hot and humid weather, his fatigue doesn't go away easily, and seeing him struggle to wake up in the morning makes me feel very sad. He says his concentration isn't what it used to be, and his food intake has decreased, so managing his physical stamina is my biggest concern. I’ve heard from others that many students take herbal tonics or Gongjindan, so I’m looking into it. Are there any trustworthy Korean medicine clinics in the Seoul area? I would prefer a place that prescribes medicine tailored to his constitution and carefully examines his condition, rather than just recommending expensive options. If anyone has actually benefited from receiving prescriptions for herbal tonics or Gongjindan, please recommend a clinic and share your experience. I'm not sure whether I should get a custom herbal medicine prepared for my child or just buy some Gongjindan to give them. As a parent, I am looking for a place I can trust and visit, so I would be really grateful if you could share your experiences.
