Hawaii’s spas fully embrace the healing benefits of ingredients from the islands’ soil and sea, relying on them as the ancient Hawaiians did when nature’s bounty was their medicine chest. They knew the value and use of every fruit, flower, leaf, root, stem, seed, bark, sap, shrub and twig, gathering this knowledge through intense training in laau lapaau (the practice of Hawaiian medicinal plant healing). Many of the same plants, herbs and other gifts of nature in spa treatments today have been used for centuries to enhance health, beauty and well-being.
These endemic and indigenous ingredients from nature — used by Hawaiians even before the first voyagers set foot or canoe on the Islands — may have unusual-sounding names, but they have time-tested therapeutic benefits.

From the Land
‘Alaea
This water-soluble red clay mixed with sea salt was a soothing salve in ancient Hawaiian medicine. Rich in minerals and mixed with essential oils, the iron oxide found in ‘alaea is said to cleanse and nourish skin; spas use it in scrubs to exfoliate, tighten and soften.
‘Awa (Kava)
Traditionally, the bitter and astringent-tasting root of the plant was pounded, mixed with water and coconut juice and consumed for medicinal and ceremonial purposes by people of the South Pacific. A mild relaxant, the root is believed to alleviate stress, anxiety, insomnia and headaches. Spas include it in soothing body wraps to help ease aches and pains and soften skin.
Ko (Sugarcane)
Ancient Hawaiians used the juice of the sugarcane to sweeten their often-bitter herbal medicines. Hawaiian turbinado sugar derived from cane is a natural antiseptic. Raw sugar’s grainy texture gently exfoliates, is much gentler than a salt scrub and aids in the hydration of dry skin.
Kukui Nut Oil
The kukui nut, also known as candlenut, has always been valued for its oil. In ancient times, the oil of the white kernels was extracted to light stone lamps and ti leaf torches. The bark, flowers and nuts all had medicinal applications. Hawaiians used the small five-petaled white flowers and the sap of the green nut to heal chapped lips, cold sores and mild sunburn and the mashed nut to relieve constipation and skin irritations. Today the rich oil is one of the best known natural sources of linoleic and linolenic fatty acids that promote healthy skin and hair and appears in body oils, shampoos and conditioners. Because it is very emollient, it is a favorite massage oil for lomilomi.
Limu (Seaweed)
Readily available at the beach, limu is a traditional remedy for coral cuts, stomachaches and general aches and pains. Seaweed, rich in minerals, is considered one of nature’s most complete nutritional sources and in scrubs and wraps helps detoxify the body and nourish skin.
Niu (Coconut)
This was once the Hawaiians’ most versatile tree, providing everything from thatching to drink to medicine. Its sweet meat yields emollient oil with a clean scent and conditioning properties for hair and skin. Heated, the oil eases muscle aches; grated, the pulp adds texture and sultry fragrance to body scrubs. The many shapes and sizes of coconut shell make it a handy massage tool.
Where to Splurge
Nature as healer is the philosophy behind even the most decadent Hawaiian spa services, which each rely on one or more native treasures. Sugar scrubs improve circulation by exfoliating dry, dead skin. Herbal wraps detoxify the body and replenish skin nutrients. Lomilomi with kukui nut or coconut oil eases muscle and joint pain. And, of course, the sweet scents of jasmine, ginger and coconut lift the spirit. Here we’ve curated a list of traditionally inspired treatments on each island. Be sure to check in with each hotel regarding their phased reopening plans for spa treatments.
