Vietnamese Herbal Steam in Hoi An: A Guide to Traditional Wellbeing

Interest in traditional Southeast Asian wellbeing practices is rising worldwide. Travellers now seek rituals that feel rooted and intentional – living traditions shaped by place, climate, and cultural continuity, not passing trends.

In Hoi An, Vietnamese herbal steam, known as Xông Hơi, remains a lasting expression of indigenous wellbeing. At Lumina Spa & Wellbeing within Namia River Retreat, the ritual flows naturally into the retreat’s wellness-inclusive rhythm. Rather than a standalone treatment, herbal steam serves as a quiet preparatory practice, supporting clarity, balance, and gentle renewal as part of daily life.

What Is Vietnamese Herbal Steam?

Vietnamese herbal steam is a traditional therapy that uses warm steam infused with fresh Vietnamese herbs. The heat gently warms the body, supports circulation, and encourages slow, relaxed breathing.

At Namia River Retreat, herbal steam is based on Southern Vietnamese herbology and prepared in two distinct formulations: one focused on physical grounding and the other on mental clarity. These blends are designed in collaboration with a local herbalist and tailored to each guest through personalised consultation.

The ritual takes place in a contemporary setting that integrates Herbal Hammam and Vichy Shower elements. Steam is maintained at a gentle temperature – approximately 36 – 38°C with soft humidity – creating a breathable, restorative environment that eases muscular tension and opens the respiratory pathways. A light Vichy rinse follows, refreshing the body and rebalancing the senses.

Rather than intensity, Vietnamese herbal steam prioritises balance. Its purpose is not to cleanse aggressively, but to relax, circulate, and restore – through warmth, breath, and rest.

Origins & Cultural Meaning

Xông Hơi – literally meaning “steam bathing” – is a long-standing practice in Southern Vietnam, passed down through generations. It is traditionally prepared by boiling medicinal herbs such as lemongrass, basil, pomelo peel, or ginger altogether in a large pot. The person receiving treatment would sit under a blanket with the pot beneath, allowing the steam to warm the body deeply and encourage sweating. This was meant to help “drive out” wind (phong), cold (hàn), and residual illness from the body.

Culturally, xông hơi is closely associated with care and recovery. It is commonly prepared for women for childbirth, for family members with flu symptoms, or anyone returning home after a long trip or physical exhaustion. The ritual represents both physical healing and emotional nurturing – a quiet act of looking after one another.

In Vietnam, herbal steam (xông hơi) is an early-response practice within herbology  (thuốc nam), using locally available plants selected by season and bodily condition. It eases colds, aches, and fatigue and remains a routine household practice nationwide. Sessions are brief (about 10 – 20 minutes) and adapted to the climate – more warming in cooler months, lighter in heat. Beyond a simple remedy, xông hơi reflects an indigenous ethic of rhythm and community shared knowledge, woven into daily life and passed down informally across generations.

How Vietnamese Herbal Steam Differs from a Turkish Hammam

While both Vietnamese xông hơi and the Turkish hammam use steam as a form of purification and relaxation, they come from very different cultural philosophies, settings, and intentions.

Vietnamese herbal steam is rooted in fresh local herbs and plant-based aromas. As previously mentioned, the steam is infused with fresh medicinal plants such as lemongrass, perilla leaf, pomelo peel, basil, and ginger, chosen for their warming and cleansing properties.

In contrast, the Turkish hammam originates from Roman bathhouse culture, and originally, it had evolved into a highly social, architectural bathing ritual. Hammams are built around large marble chambers with dry heat and controlled steam. Rather than herbal therapy, the emphasis is on deep cleansing through water, soap, exfoliation, and massage. 

In essence, Vietnamese herbal steam is a private, plant-based practice focused on internal restoration, while the Turkish hammam is a communal bathing tradition centred on physical cleansing

A Local Expression of Herbal Steam in Hoi An

At Namia River Retreat, many of the herbs used in the steam ritual are grown in the resort’s own garden or sourced from nearby communities. Each plant is chosen for its traditional role and sensory quality, rather than clinical claims.

Notable herbs include:

• Sả (Lemongrass): Known for clarity and purification, with a fresh aroma that also acts as a natural mosquito repellent
• Lá lốt (Piper lolot leaf): Traditionally used to warm the body and support circulation
• Ngải cứu (Mugwort): Associated with restoring vitality and awakening energy
• Hương thảo (Rosemary): Adds a grounding, familiar aromatic note
• Bồ ngót, khúc khắc (Sweet leaf, Smilax glabra): Common in Vietnamese folk practices

Together, these herbs create a sensory experience that feels distinctly local – earthy, clean, and quietly restorative. The focus remains on presence and continuity, not outcomes.

The Herbal Steam Ritual at Lumina Spa & Wellbeing (Namia River Retreat)

At Lumina Spa & Wellbeing, the Herbal Hammam Steam is part of Namia’s Daily Wellness Journeys and is offered complimentary to all in-house guests, available once per day per person. Booking is required before arrival at the spa, and guests are advised to stay well hydrated before their session to ensure a comfortable and safe experience.

The Apothecary

Each experience begins at The Apothecary, where guests receive a personalised herbal recommendation following a brief wellbeing consultation. Herbs are prepared by Namia River Retreat’s resident herbalist using plants grown on-site and sourced from trusted local growers. This space functions as a living herbal library – a place of selection, preparation, and quiet guidance.

Private Herbal Steam Chambers

Lumina Spa features eight private, solo-use hammam rooms, ensuring complete privacy and a maximum of eight guests at any one time.

• Steam temperature: 36 – 38°C with gentle humidity
• Heated stone bed: 35 – 37°C, supporting full-body relaxation
• Integrated Vichy shower for light cleansing

The environment feels enclosed yet breathable, encouraging slow breathing and physical ease without strain.

The Vietnamese Hammam Layer

Inspired by traditional hammam rituals, this layer reinterprets the concept through Vietnamese herbology and material language.

The ritual combines:

• Herbal steam
• Herbal exfoliation
• Herbal body wrap

Rather than a cleansing focus, steam is used as a sensory and preparatory step, helping release stored tension and allowing the body to receive subsequent therapy more fully. The experience is individual, ritual-focused, and grounded in three core elements: earth, aroma, and water.

Accompanying Rituals

Hydration is integral to the process.

Throughout Lumina Spa, custom-designed water stations offer three options:

• Mineral water (Calcium & Magnesium)
• RO water
• Alkaline water

Following spa therapy, the herbalist prepares personalised in-room rituals – either a herbal bath blend or calming herbal tea – to be enjoyed later in the evening. These quiet continuations allow the ritual to extend beyond the spa space.
