How a Herbalist Thinks About Eczema — Elimination, Constitution, and the Gut-Skin Axis

Eczema is one of the conditions most likely to bring someone to herbal medicine after conventional treatment has produced only partial results. The conventional approach — topical steroids, emollients, antihistamines — manages the skin surface. It does not address why the skin is reacting in the first place, and for many people, the pattern continues for years, flaring and subsiding without any clear trajectory toward resolution.

A herbalist working with eczema is working with a systemic condition that happens to express itself on the skin.

Skin as an elimination organ

The skin is one of the body's four primary elimination routes, alongside the liver, kidneys, and lungs. When any of the other elimination pathways is under load or insufficient, the burden shifts — and the skin compensates. This is clinically significant for eczema, because in many cases the skin is doing the work that the gut, liver, or lymphatic system is not doing adequately.

A herbalist will therefore always be asking about digestion, about bowel regularity, about liver function, and about lymphatic circulation in an eczema case. The skin condition may be the presenting complaint, but it is rarely where the treatment begins.

The gut-skin axis

The relationship between gut health and skin health is now well supported in research, though herbalists have been working with it clinically for generations. A compromised gut lining — increased intestinal permeability — allows partially digested food particles, bacterial endotoxins, and inflammatory mediators to enter the bloodstream, triggering systemic immune responses that express themselves, in genetically susceptible individuals, as atopic conditions including eczema. The microbiome is deeply involved: specific bacterial communities in the gut influence the regulatory T-cell responses that modulate allergic reactivity.

Supporting gut integrity is therefore foundational in herbal eczema treatment. Marshmallow root (Althaea officinalis) and meadowsweet (Filipendula ulmaria) support mucosal repair. Herbs that encourage healthy microbiome diversity — through their prebiotic fibre content, through their bitter stimulation of digestive secretion — are incorporated alongside more directly soothing herbs.

Constitutional reading

The constitutional dimension of eczema is one that herbal medicine attends to carefully. The classic eczema constitution in traditional Western herbal medicine is the lymphatic type — fair skinned, prone to swollen glands, carrying a tendency toward catarrhal and inflammatory conditions, with a system that struggles to process and eliminate efficiently. The iridological equivalent — a blue or grey iris with a pronounced lymphatic wreath, lacunae in the skin zone, signs of elimination burden — confirms and deepens this constitutional reading.

Treatment for a lymphatic constitution will prioritise lymphatic drainage and elimination support: cleavers (Galium aparine) — the great lymphatic herb of the spring — alongside burdock root (Arctium lappa), which works on both the lymphatic system and the liver, and has a long clinical history in skin conditions. Red clover (Trifolium pratense) supports lymphatic movement and has additional anti-inflammatory properties.

Where the liver is under load — a common finding in chronic eczema, particularly where the condition is accompanied by food intolerances, chemical sensitivities, or a history of frequent medication use — milk thistle (Silybum marianum) and dandelion root (Taraxacum officinale) are included to support hepatic clearance.

Where the nervous system is driving or worsening the pattern — eczema notoriously responds to stress — nervine support is incorporated alongside the elimination and gut work.

A small aromatic mover — chamomile (Matricaria chamomilla), which has both anti-inflammatory and nervous system calming properties — serves as the circulatory and moving element in the formula, with the additional benefit of its direct anti-inflammatory action on the skin terrain.

Topical support

Alongside the internal prescription, topical herbal preparations have a significant role in soothing and protecting the skin surface. Calendula (Calendula officinalis) cream or infused oil supports tissue repair and reduces inflammation at the skin level. Chickweed (Stellaria media) is specific to the intense itching that makes eczema so difficult to endure. These are supportive measures, not the primary treatment — but they matter for quality of life while the systemic terrain is being addressed.

If your eczema has never fully resolved

Chronic eczema that responds to steroids but returns when they are stopped is a systemic pattern, not a skin problem. The skin is asking for something that the surface treatment cannot provide. Initial consultations are available at Sussex Herbal through the website.

Acne in Adults: Liver, Hormones, and Lymphatic Load

Adult acne — particularly in women, and particularly acne that worsens in the premenstrual phase — is one of the most common skin presentations in clinical herbal practice, and one of the most straightforwardly addressable from a terrain perspective. It is also one of the conditions most poorly served by the conventional treatment ladder, which tends toward antibiotics, topical retinoids, and ultimately hormonal contraception — each of which addresses the symptom while leaving the underlying terrain entirely undisturbed.

A herbalist working with adult acne is always working with liver function, hormonal balance, and lymphatic load — because these are, in most cases, where the pattern originates.

Why adult acne is different from teenage acne

The acne of adolescence is primarily driven by the surge of androgens at puberty, which increases sebum production and creates the conditions for bacterial proliferation and inflammation in the hair follicle. It is, broadly speaking, a normal physiological response to a normal hormonal transition — and in many people it resolves as that transition completes.

Adult acne, by contrast — particularly the cystic, hormonally linked acne that clusters around the jaw, chin, and lower face — is driven by a different set of mechanisms. Hormonal imbalance, specifically an excess of androgens relative to oestrogen, plays a central role. But the reason androgen excess develops in adulthood is almost always a systemic one: impaired liver clearance of androgens, insulin resistance driving ovarian androgen production, a microbiome that is not clearing oestrogenic metabolites efficiently, or chronic low-grade inflammation that raises androgen sensitivity throughout the skin.

The liver connection

The liver is responsible for metabolising and clearing androgens — testosterone, DHEA, and their derivatives — from the circulation. When liver function is suboptimal, androgen clearance is impaired, circulating androgens remain elevated for longer, and sebaceous glands — which are androgen-sensitive — respond by producing more sebum.

This is why liver support is foundational in adult acne treatment, and why it so often produces results where topical treatments alone have not. Milk thistle (Silybum marianum) protects and regenerates hepatic tissue and supports detoxification capacity. Dandelion root (Taraxacum officinale) stimulates bile flow and supports the excretion of hormone metabolites. Burdock root (Arctium lappa) addresses both the liver and the lymphatic system, and has a long traditional use specifically in inflammatory skin conditions.

The lymphatic dimension

The lymphatic system is the terrain's drainage and immune network, and when it is sluggish — which it is in many people with chronic skin conditions — the skin carries a higher burden of inflammatory and metabolic waste than it should. Cleavers (Galium aparine), red clover (Trifolium pratense), and burdock root (Arctium lappa) are the primary lymphatic herbs in this context, supporting the system's capacity to clear the load that is expressing itself through the skin.

Hormonal prescription

Where the hormonal dimension is prominent — clear premenstrual worsening, associated PMS, or confirmed androgen excess — chaste tree (Vitex agnus-castus) supports ovulatory function and progesterone production, redressing the hormonal balance from the pituitary downward. Spearmint (Mentha spicata) adds a direct anti-androgenic effect at the tissue level.

Rose (Rosa damascena) serves as the aromatic mover in adult acne prescriptions — its affinity with the female hormonal terrain, its lymphatic action, and its anti-inflammatory properties at the skin level make it an almost universal inclusion.

A terrain that needs time

Hormonal and lymphatic acne does not resolve in weeks. The terrain that has created the conditions for it has usually been developing over months or years, and reversing it requires consistent, systemic support over a comparable timescale. The reward for that patience is not just clearer skin but a genuinely improved hormonal and eliminatory terrain — one that supports health in ways that extend considerably beyond the presenting complaint.
