Itchy skin and natural support for lasting relief

You may notice that itching can appear without a clear external cause, or persist despite using topical treatments. Why? A broader approach looks beyond temporary relief and focuses on supporting overall internal balance.

Understanding itchy skin (pruritus)

Itchy skin, also known as pruritus, is characterised by an uncomfortable sensation that creates the urge to scratch. It may occur in specific areas or across the whole body and can range from mild irritation to more persistent discomfort.

Episodes of itching may come and go or last for extended periods. While external factors such as dryness or irritants can all contribute, internal influences may also play a big role in ongoing or recurring symptoms.

What is happening in the body when itching occurs (1,2)

Itching is often linked to signals sent through the nervous system, triggered by the release of certain compounds such as histamine.

These signals can be influenced by immune responses, skin barrier integrity, and levels of inflammation within the body.

When the skin barrier is compromised, it may lose moisture more easily and become more reactive to environmental factors. At the same time, internal processes can influence how sensitive the skin becomes, increasing the likelihood of persistent itching.

Common contributing factors linked to internal systems

Gut health

The digestive system plays an important role in overall balance. Disruptions in gut bacteria or increased intestinal permeability may allow substances to circulate in the body that can contribute to skin sensitivity in general. This is also particularly prevalent in cases of atopic dermatitis (3).

Liver function

The liver is involved in processing hormones and other substances. When this process becomes less efficient, the body may rely more on alternative pathways of elimination, which can sometimes include the skin. Pruritus (itch) is a common complication of cholestatic liver diseases (CLD) (4).

Immune response

Heightened immune activity may increase sensitivity to certain foods or environmental exposures. This can contribute to the release of inflammatory compounds that affect the skin (5).

Stress and the nervous system

Stress can influence both immune and skin function. Ongoing tension may affect the skin barrier and increase sensitivity, making itching more noticeable or persistent (6).

Environmental and lifestyle factors

Exposure to irritants such as harsh skincare products, temperature changes, or fabrics can aggravate the skin. Hydration levels, sleep quality, and daily habits may also influence how the skin responds (7).

Natural support approach

Key ways to support the body through itchy skin

Supporting the body often begins with creating consistent daily habits. Regular meals that include protein, healthy fats, and fibre can help maintain stable energy levels and support overall balance.

Including a variety of whole foods also contributes to adequate nutrient intake for skin health.

Hydration plays an important role in maintaining skin moisture and resilience. In some cases, adding mineral-rich fluids may support fluid balance more effectively than water alone.

Nutritional support

Nutrients such as omega-3 fatty acids are often included to help maintain normal inflammatory balance (8). Vitamins and minerals, including zinc and vitamin D, are also involved in skin repair and immune function (9).

Herbal support for itching skin

Topical applications such as creams or oils containing calming plant extracts may provide a soothing effect on the skin. Certain herbs are also traditionally used to support relaxation and help the body respond to stress more effectively.

Common calming plant extracts:

Centella Asiatica (Cica): Rich in triterpenoids like madecassoside, it is widely used to promote wound healing, moisturise, and soothe sensitive or damaged skin.

Chamomile: Contains bisabolol and chamazulene, which act as natural anti-inflammatories to quickly reduce itching, redness, and irritation.

Aloe Vera: Provides an immediate cooling effect and deep hydration through its polysaccharides, making it great for hot and inflamed, or sunburnt skin.

Calendula (Marigold): Packed with flavonoids and carotenoids, it supports the skin's natural healing process and is gentle enough for baby products.

Green Tea: Contains high levels of EGCG (epigallocatechin gallate), a potent antioxidant that reduces UV-induced inflammation and helps regulate oil production.

Oregon grape: is effective for itchy, inflamed skin conditions like psoriasis and eczema due to its high concentration of berberine, a compound with strong anti-inflammatory, antimicrobial properties.

Meanwhile, nervine relaxant herbs such as chamomile, lavender, passionflower, lemon balm, valerian root and skullcap are commonly used to promote natural relaxation in ways such as calming racing thoughts, easing muscle tension and supporting sleep. This can be particularly helpful during periods of heightened stress or anxiety (whereby the skin might flare up as a result).

Lifestyle habits for reducing irritation

Daily habits can influence how the skin behaves over time. Gentle skincare routines that avoid harsh ingredients and synthetic chemicals may help to better protect the skin barrier.

Wearing breathable fabrics and maintaining a comfortable indoor environment can reduce external irritation. Simple practices such as regular movement, stretching, and relaxation techniques may also support overall balance.

Sleep and recovery

Rest plays a key role in skin repair. A consistent sleep routine and a calming evening environment may help support the body’s natural recovery processes and reduce the likelihood of ongoing irritation.

Fungal infections

Fungal infections cause itching, and are a common culprit, because the fungi damage the skin's surface and trigger an inflammatory immune response. Fungi, such as dermatophytes or yeast, feed on keratin and produce waste, which causes irritation, red rashes, and scaling. Essentially, this irritation activates the nerves, as well as immune cells, resulting in itching or burning.

When to see a medical professional about itching skin

While most itching is harmless, it can sometimes signal serious internal conditions like liver disease, kidney failure, or certain cancers (10). If your itching skin symptoms are severe and/or persistent, seeking the guidance of a medical professional is advised.

Main takeaways

Itchy skin can be influenced by a combination of internal and external factors. Supporting digestion, immune balance, hydration, and stress management may help reduce underlying triggers. Over time, consistent daily habits can support healthier skin function and improve overall comfort.
