Botanical Bust Enhancement: Research, Guide

Dihydrotestosterone (DHT) reducing herbs

Winter squash (pumpkin) seeds, pygeum bark, nettle, saw palmetto, oats and possibly legumes have effects of reducing 5alpha-dihydrotestosterone (DHT). Oddly, many of these herbs also have in common of reducing aromatase enzymes, when used in large amounts. Aromatase is the conversion of androgens into estrogens. Reducing estrogen capacity does not assist with breast enlargement. There is a role for squash seeds and possibly oats in breast enhancement, but they cannot be the main part of a regimen for it to be successful.

Also, many of these herbs have a reputation for primary use for male health.


Winter Squash (Cucurbita) Seeds

Winter squash seeds, including pumpkin seeds, lower dihydrotestosterone and estrogen conversion from other androgens.

Saw Palmetto (Serenoa)

Aside from lowering DHT and reducing production of estrogen, Saw Palmetto also raises Luteinizing Hormone (LH), and lowers prolactin.

Pygeum (Prunus africanus)

Pygeum (Prunus africanus) or African plum tree is known for its effects on reducing DHT.

The Prunus genus includes cherries, plums, apricots, nectarines, almonds and peaches. Many barks of the Prunus genus contain the same hormonal properties as pygeum. Prunus domestica, P. persica, P. amygdalus, P. cerasoides and P. armeniaca can substitute Prunus africanus. As there is a danger of cyanide from bitter almonds, seeds and leaves of other Prunus species, there is uncertainty of safety from bark from other species of Prunus.

Nettle (Urtica)

Nettle has a reputation to lower DHT. It has diuretic properties

Oats (Avena)

Oats has a reputation to lower DHT.

Legume (Fabaceae) family

Equol, a metabolite of daidzen and genistein, which comes from soy and other legumes binds to the hormone DHT. In large amounts, equol reduces aromatase capacity.

Corn (Zea)

Equol is also contained in corn, and perhaps in corn parts. It binds to DHT, but in large amounts equol reduces aromatase capacity.

Reishi (Ganoderma)

Hot flashes and other symptoms are often reported with reishi. Red Reishi lowers DHT, but it also has anti-estrogenic properties.

Lavender (Lavandula)

Lavender lowers DHT, and it is mildly estrogenic.

Tea tree (Melaleuca)

Topical tea tree oil lowers DHT, and it is mildly estrogenic.


For any DHT lowering herb that reduces aromatase capacity, no more than 75mg in solid form should be taken per occasional day as tea. Prunus bark and Nettle may have diuretic or metabolic properties, so these may slow down breast enlargement progress.

Do not use Reishi or any herb that has a reputation for causing hot-flashes when there is an androgen excess. If reishi or herbs with similar properties are going to be used, no more than a peasized amount should be used per day.

Lavender and tea tree only work for breast enhancement when taken with a herb like fenugreek or mint. Lavender and tea tree oils should not be taken internally, and they should be diluted before topical use.

Most DHT lowering herbs do not work for bust enhancement when there is androgen excess.
