Traditional Korean Medicine treatment for cold hands and feet

An acquaintance has Raynaud's phenomenon. They went to a general hospital to receive treatment for Raynaud's and tried various treatments, but they said there was little effect.

However, it seems that a friend's parents forcibly took her to a traditional Korean medicine clinic to have infrared thermal imaging done, analyze the cause, and receive customized herbal medicine.

My friend doesn't know anything about traditional Korean medicine and has never experienced it, so she's worried about whether it's effective or just expensive.

I heard that the herbal medicine is called Danggui Boghyeoltang, as the traditional Korean doctor mentioned.

But since the price is a bit high, my parents are unsure and hesitant to proceed just based on what they've heard.

Has anyone received traditional Korean medicine treatment for cold hands and feet? If so, I would like to hear whether it was effective.
