For allergic rhinitis, the recommended dosage is 600 mg of dried nettle leaf per day taken in three separate doses.[1]

In benign prostatic hyperplasia (BPH), a daily dose of 360 mg of aqueous root extract taken as 3 divided doses is suggested for up to 6 months.[2] Alternatively, methanol root extract of up to 1,200 mg daily, also as three divided doses, can be used for up to 9 weeks.[3] While these doses are used in trials, there is no clear evidence-based dose as yet, and there are wide variations in the doses used for the other potential benefits.
