Nettle Root and the Prostate: What Memorial Sloan Kettering Reports
Memorial Sloan Kettering says studies suggest nettle may relieve symptoms of benign prostatic hyperplasia, usually combined with saw palmetto or pygeum, so the single-herb effect is unclear, and that more studies are needed. It lists allergic reactions and one low-blood-sugar case. SodaPeak lists nettle extract fourth, and this site makes no prostate claim.

MSK01
What does MSK say about nettle?
That studies suggest possible symptom relief, but more studies are needed.
For benign prostatic hyperplasia, nettle is usually combined with saw palmetto or pygeum, so the effect of the single herb is unclear, and some cited studies used other plant parts such as leaf or seed oil (MSK, Nettle). That matters because SodaPeak names an extract and no plant part.
| Topic | Note |
|---|---|
| BPH symptoms | May relieve; usually studied in combination |
| Plant parts | Some studies used leaf or seed oil |
| Blood sugar | Leaf extract in a diabetes trial; one low-blood-sugar case |
| Other cases | Breast enlargement in a man drinking tea, hives, allergic rhinitis |
| Animal data | May add to blood pressure medicines and diuretics |

Where does nettle sit on the label?
Fourth, as nettle extract, with a ceiling of 300 mg per serving and no stated amount.
The ceiling is arithmetic from the blend rule (21 CFR 101.36 (eCFR)). See the nettle root page for the plant, and the side effects page for the cautions by name.

- 2Tongkat ali0
- 3Saw palmetto0
- 4Nettle root0
- 5Wild yam0
- 6Sarsaparilla0
- 7Orchic substance0
- 8Boron amino acid chelate0
Each bar is the most that line can weigh once line 1 is set: at most the weight of line 1 (the list runs from heaviest to lightest) and at most the remainder shared by the lines above it. These are ceilings from arithmetic (21 CFR 101.36 (eCFR)), not the real amounts.
Medicines03
Who should be careful?
People on blood pressure medicine, water pills or diabetes medicine.
The animal data and the blood-sugar case are reasons to ask a prescriber. NCCIH advises telling all your health care providers about every supplement (NCCIH, Using Supplements Wisely).
