In plain English

Adults with Graves' disease who take Haizao Yuhu Decoction along with methimazole report better quality of life and fewer symptoms after 12 weeks than those who take methimazole alone.

See the scientific wording

In adults with Graves' disease, adding Haizao Yuhu Decoction to methimazole is associated with greater improvement in patient-reported quality of life, as measured by ThyPRO39 scores (14.06 vs 16.10) and TCM syndrome scores (5.47 vs 6.69) after 12 weeks, indicating better symptom control and well-being.

Why this might work

High iodine from the herbal decoction blocks the thyroid from making too much hormone, while also cutting off its blood supply. This reduces the overactive thyroid's output and calms the immune system's attack on the gland. As a result, inflammation drops, side effects from the standard drug decrease, and patients feel less tired, irritable, and unwell.
