Anti androgens 
- Vitex agnus-castus (Chaste tree)
- Paeoniae lactiflora (White peony)
- Camellia sinensis (Tea plant)
- Mentha spicata (Spearmint)
- Ganoderma lucidum (Red reishi)
- Glycyrrhiza glabra (Liquorice)
NOTE: Liquorice is known to cause high blood pressure with extended use. This can add to the risk of blood clots already present when taking estrogenic agonists! 
- Pueraria Mirifica (White Kwao Krua) 
- Humulus lupulus (Common hop) 
- Equus ferus caballus (Pregnant Mare Urine) 
- Juglans regia (English walnut) 
Extended treatment with some non-synthetic sources of hormone replacement therapy is highly experimental and very little is known about it's long term effects. In the case of phyto- or xeno- hormones some are so obscure that it could be difficult to test for their blood concentration levels and thus proper regulation of dosage is impaired. In addition, dosage regulation is further impaired unless a proper extraction of the active constituent(s) is made, as the amount of substance in a given organism can vary batch to batch.
