Spearmint
An honest look at the mellow mint with genuine, if early, research interest in hormonal balance
Spearmint is the gentler, sweeter mint, and it is more than a flavour: small trials have studied its anti-androgen effect in women with hormonal imbalance, and it has a long tradition as a digestive herb. Sippo Quiet Hours uses it for its soft character and genuine, if early, research interest. It is a pleasant daily cup with some interesting science, not a hormonal treatment. For hormonal concerns, work with your doctor.
Spearmint usually plays second fiddle to peppermint, but it is the more interesting of the two. Beyond its mellow, sweet flavour, small studies have looked at spearmint's effect on hormones, and it carries a long digestive tradition. Quiet Hours leans on it, so this page lays out what is genuinely known, and what is still early.

People also ask
Spearmint is a mellow, caffeine-free mint with two things going for it: a long traditional use as a soft digestive herb, and genuine, if early, research interest in hormonal balance. Small randomised trials found spearmint tea reduced testosterone levels in women with hormonal imbalance (Grant, 2010; Akdoğan et al., 2007). We frame it honestly as an interesting, well-tolerated herb, not a treatment.
There is a real but early signal. The trials were small and short, and a tea is not a treatment for any hormonal condition. So we would say spearmint is a genuinely interesting herb with some research behind it, worth enjoying as a daily cup, but if you are managing a hormonal condition, work with your doctor. We cover this in detail on our spearmint and hormonal balance guide.
Yes. Quiet Hours is a herbal blend with no tea leaf, so you can enjoy spearmint any time, including the evening.
For most people it is a gentle everyday tea. If you are pregnant, breastfeeding, on medication or managing a hormonal condition, check with your doctor first.
Spearmint, in depth
Spearmint and peppermint are different plants with different characters. Peppermint is sharp, cooling and high in menthol; spearmint is mellow, sweet and far gentler, which makes it the easier mint to drink in quantity and the kinder one on a sensitive system. That softness is why it leads our Quiet Hours blend.
Spearmint is unusual among everyday herbs in having a small but real body of hormonal research. Two randomised trials found that drinking spearmint tea reduced free and total testosterone in women with hormonal imbalance over several weeks (Grant, 2010; Akdoğan et al., 2007). That is a genuine signal, and an unusual one for a common kitchen herb, which is what makes spearmint worth a closer look.
Those trials were small and short, and a tea is not a treatment for any hormonal condition. The effect on visible symptoms was modest and did not always reach significance. So the right framing is: spearmint is a well-tolerated herb with a genuine but early research signal, best enjoyed as a daily cup, not relied on as a remedy. If you are managing something hormonal, your doctor leads.
Steep it a good few minutes for a full, mellow flavour. It is lovely after a meal in the digestive-mint tradition, and because it is caffeine free it doubles as an evening cup. For the hormonal-balance angle specifically, our dedicated spearmint guide goes deeper.

Drinking spearmint tea twice daily for 30 days reduced free and total testosterone in women with PCOS. Small trial; the reduction in visible hirsutism approached but did not reach significance. Genuine signal for the ingredient, not a treatment claim.

Spearmint tea reduced free testosterone in women with hirsutism over a short intervention. Very small and brief; supports the anti-androgen direction, not a clinical promise.

Chamomile extract reduced generalised anxiety symptoms versus placebo over 8 weeks. Used a standardised extract, not tea, so cited for the calming mechanism behind a soothing ritual, not as proof a teabag treats anything.
