Aromatherapy for Hormones

Hormones play an essential role in our physical and emotional wellbeing. They influence our menstrual cycles, fertility, sleep, mood, energy levels, skin and so much more. When our hormones fluctuate, whether during the menstrual cycle, perimenopause or menopause, we may notice changes that affect our everyday lives.

As a clinical aromatherapist, I find the relationship between essential oils and hormonal wellbeing a fascinating area of study. Certain essential oils contain naturally occurring chemical constituents that have been investigated for their potential hormone-related activity. Understanding these constituents helps us make informed choices when selecting oils to support clients through different stages of life.

Essential oils are complex mixtures of volatile aromatic molecules, each with its own chemical structure and biological properties. Some constituents have been investigated for their potential to interact with hormonal pathways, while others may be more relevant to aromatherapy through their effects on relaxation, mood and the stress response.

Several constituents are particularly interesting when exploring the relationship between essential oils and hormonal health:

• Anethole, a methyl ether, found in fennel, aniseed and star anise.

• Eugenol, carvacrol and thymol, phenolic constituents found in oils such as clove and thyme.

• Matricaria methyl ester, a constituent associated with German chamomile.

• Viridiflorol, a sesquiterpenol found in niaouli.

• Sclareol, a diterpenol found in clary sage.

  
  

Research into these compounds varies considerably. Some findings come from laboratory experiments or animal studies, while other traditional uses are based on clinical experience and anecdotal reports. Evidence of activity in an animal or laboratory setting does not necessarily mean that an essential oil will produce the same effect in humans.

Anethole is an aromatic constituent found in fennel (Foeniculum vulgare), aniseed (Pimpinella anisum) and star anise (Illicium verum). It has attracted interest because of its potential oestrogen-like activity.

Oestrogen is involved in regulating the menstrual cycle and maintaining various tissues throughout the body. As oestrogen levels fluctuate and decline during the menopause, some women experience symptoms such as hot flushes, changes in mood, vaginal dryness and disrupted sleep.

Anethole has demonstrated oestrogen-like effects in animal research, although its activity is considered weak and its effects in humans remain uncertain. Historically, fennel and aniseed have also been associated with menstrual and lactation-related uses.

Phenolic constituents such as eugenol, carvacrol and thymol are known for their biological activity. Eugenol occurs prominently in clove oil (Syzygium aromaticum), while thymol and carvacrol are found in certain thyme and oregano oils.

These compounds have been investigated for a range of effects, including antimicrobial and pain-related mechanisms. Some aromatherapy teaching texts also discuss their potential influence on the adrenal cortex and prostaglandin-related pathways.

From a clinical aromatherapy perspective, these oils are generally selected for specific purposes rather than as first choices for hormonal support. Phenol-rich oils can also present significant skin-irritation risks, so appropriate dilution and safety guidance are essential.

German chamomile (Matricaria chamomilla) is well known in aromatherapy for its soothing, calming and anti-inflammatory properties. It is often chosen when the aim is to support relaxation and comfort.

Older aromatherapy literature discusses a constituent known as matricaria methyl ester in connection with hormone-related activity and delayed puberty. German chamomile may have a valuable place in a holistic treatment plan. Relaxation, emotional reassurance and a calming therapeutic experience can be helpful when a client is navigating menstrual discomfort, stress or the changes associated with perimenopause and menopause.

Viridiflorol is a sesquiterpenol found in several essential oils, including niaouli (Melaleuca quinquenervia). Some aromatherapy texts describe it as having oestrogen-like properties and discuss its traditional use in relation to menstrual regulation and menopausal changes. Niaouli has also been studied and used for other purposes including rheumatism, brain fog and respiratory support.

Clary sage (Salvia sclarea) is perhaps one of the best-known essential oils in discussions of aromatherapy and women's wellbeing. It contains sclareol, a diterpenol that has attracted scientific interest because of its structural and biological characteristics. Older aromatherapy literature sometimes describes sclareol as resembling oestrogen and associates clary sage with menopausal symptoms, including hot flushes and changes in skin condition.

Clary sage is a popular choice in aromatherapy for its distinctive herbal, earthy aroma and its traditional association with relaxation and women's health. It may be incorporated into a personalised blend to support a calming treatment experience, particularly when stress and emotional wellbeing are important considerations.

One of the most important principles of clinical aromatherapy is that we do not need to focus solely on hormones when supporting someone through hormonal change. Hormones, perimenopause and menopause can affect many aspects of life. A client may experience disturbed sleep, anxiety, irritability, reduced confidence, changes in body image or difficulty managing everyday stress. These experiences are influenced by a combination of biological, psychological and social factors.

A carefully selected essential oil blend can become part of a wider self-care routine. Depending on the individual's needs and preferences, this might involve a relaxing massage, a familiar evening aroma, or a calming ritual designed to encourage rest and relaxation.

Hormonal transitions can be challenging, but they can also be approached with compassion, understanding and appropriate support. By selecting essential oils thoughtfully and focusing on relaxation, emotional wellbeing and the needs of the whole person, aromatherapy can form a meaningful part of a wider approach to self-care.

At Aroma Heart Holistics, I believe aromatherapy is about supporting the whole person — mind, body and emotional wellbeing — through the different stages of life.
