Some of the most touching examples of traditional botanical bathing come from Hakka communities in Guangdong, China.

​

A 2026 ethnobotanical study investigated herbal bathing practices associated with postpartum care and infant care across 19 Hakka settlements.

Researchers interviewed 138 participants and documented 108 plant species used in traditional medicinal baths.

​

These preparations often involved combinations of three to five plants, typically boiled in water before being used for washing or bathing.

What makes this tradition especially meaningful is the role of family.

​

Knowledge of botanical preparations was frequently held by older women, including mothers, grandmothers, and other caregivers.

Plants were gathered, dried, stored, and prepared as part of family care practices.

​

The study described how herbal bathing knowledge was passed between generations through everyday experience and oral tradition.

For these families, preparing a bath could be more than a practical task. It was also an expression of caregiving and cultural continuity.

The researchers documented traditional beliefs about postpartum recovery and infant health. These beliefs are important cultural information, although they should not be confused with evidence that herbal baths can prevent or treat medical conditions.

​

A note on modern care: Historical postpartum and infant bathing preparations should not be recreated for newborns or recovering mothers without appropriate medical guidance. Some traditional plants, concentrations, and water temperatures may be unsuitable or unsafe.

​

Japan offers a particularly lovely example of bathing in actual tea.

​

Japanese bathing culture includes public bathhouses known as sento and natural hot spring baths known as onsen.

While these bathing traditions have their own extensive histories, certain establishments also offer botanical bathing experiences.

One documented example can be found in Ureshino, Saga Prefecture, a region known for its tea production.

At the Warakuen inn, visitors can experience a distinctive green tea bath called Ryokusen.

The establishment describes a large stone teapot in which locally grown Ureshino tea is steeped. Tea-infused water then flows into the bathing area.

​

According to Warakuen, this particular tea bath opened in September 1996.

Although it is a relatively modern attraction, it beautifully brings together two important elements of Japanese culture: tea appreciation and bathing.

​

It's also a reminder that traditions continue to evolve. Modern botanical bathing experiences can celebrate cultural heritage without necessarily being ancient practices themselves.

​

​

​

Green tea contains naturally occurring polyphenols, including compounds called catechins.

These substances have been studied for their antioxidant properties and potential applications in skin care.

However, there is an important difference between research on isolated tea compounds and evidence that bathing in brewed tea produces measurable skin benefits.

​

A small clinical pilot study involving 20 participants with atopic dermatitis examined bathing with green tea extract over four weeks. Researchers did not find significant improvements in the measured outcomes.

So while a green tea bath may offer a pleasant sensory experience, current evidence does not establish it as an effective treatment for eczema or other skin conditions.

​

Sometimes the enjoyment of a warm, fragrant bath is reason enough.

​

​

​

In Korea, the traditional holiday of Dano offers another example of plants being incorporated into seasonal washing rituals.

Dano falls on the fifth day of the fifth lunar month and has historical connections to agricultural life and seasonal observances.

One traditional custom involves women washing their hair in water prepared with changpo, commonly translated as sweet flag.

​

The Korea Tourism Organization continues to document this practice as part of the holiday's cultural heritage.

​

Unlike the green tea baths of Japan, this is not a tradition of bathing in Camellia sinensis tea.

​

Instead, it demonstrates the broader historical use of botanical water preparations for personal care and seasonal observance.

It also reminds us that botanical bathing traditions are wonderfully diverse. Some involve full-body immersion, while others focus on washing the hair, hands, or particular parts of the body.

​

​

​

​

When we compare these traditions, several themes emerge.

​

Plants as part of everyday care.

​

Botanical preparations were incorporated into household routines, including bathing, washing, and traditional approaches to physical well-being.

​

Seasonal observances.

 

Some bathing customs were connected to festivals, agricultural calendars, and ideas about renewal or protection.

​

Knowledge passed between generations. Botanical knowledge was often learned through families, community practices, and direct experience rather than written instructions.

​

​

Relationships with local environments.

 

Traditional preparations frequently relied on plants available within particular landscapes and ecosystems.

​

These shared themes do not mean that all botanical bathing traditions have the same origins or meanings.

Each belongs to its own cultural and historical context.

​

But together, they illustrate the many ways people have found meaning in the simple combination of plants and water.
