Why Does Sea Buckthorn Make You Wet?

A Scientific Look at Sea Buckthorn's Effects on Moisture and Lubrication

Sea buckthorn (Hippophae rhamnoides) has earned a reputation as a functional superfood, used for centuries in traditional medicine across Asia and Europe. Its nutrient-dense berries are celebrated for their vivid orange color and impressive profile of vitamins, antioxidants, and healthy fatty acids. Recently, public and professional interest in sea buckthorn has centered on one intriguing and specific effect: its ability to promote "wetness" or enhance bodily moisture, particularly the lubrication of mucous membranes. But what is the scientific basis for this? Is there evidence to support the claim that sea buckthorn makes you "wet," and if so, how does it work?

This article takes an in-depth look at the mechanisms, available research, and uses of sea buckthorn in the context of promoting internal and external moisture.

Understanding Sea Buckthorn: Nutritional Profile

The berries, oil, and leaves of the sea buckthorn plant are rich in vitamins (notably vitamin C, E, and A), minerals, flavonoids, and fatty acids. What sets sea buckthorn apart from many other botanicals, however, is its rare and comprehensive fatty acid profile. The berry pulp and seed oils contain:

- Omega-3 (alpha-linolenic acid)

- Omega-6 (linoleic acid)

- Omega-7 (palmitoleic acid)

- Omega-9 (oleic acid)

Of particular interest is omega-7 (palmitoleic acid), which is found in high concentrations only in a small group of plant sources—sea buckthorn being the most prominent. Omega-7 fatty acids have been linked to the support and maintenance of mucosal health throughout the body.

What Does "Wet" Mean in This Context?

In discussions about sea buckthorn, "wet" typically refers to the support of natural lubrication and moisture of the body’s mucous membranes. These membranes line the eyes, mouth, vaginal tract, respiratory tract, and digestive system, and their ability to remain adequately hydrated is critical for comfort and health. 

When mucous membranes become dry, it can lead to symptoms such as dry eyes, dry mouth, vaginal dryness, and uncomfortable skin. These symptoms may be exacerbated by factors such as aging, menopause, certain medications, dehydration, or autoimmune conditions such as Sjögren's syndrome.

How Sea Buckthorn Supports Moisture and Lubrication

The unique fatty acid profile of sea buckthorn—especially omega-7—appears to play a pivotal role in hydrating and repairing mucosal tissues. Here’s how:

1. Omega-7 Fatty Acids:  

Omega-7 is involved in constructing and maintaining the health of cell membranes, which form the barrier of mucous membranes. By nourishing these cells, omega-7 helps maintain their integrity and encourages healthy secretion of natural lubricants and moisture.

2. Anti-Inflammatory and Antioxidant Effects:  

Sea buckthorn’s antioxidants reduce oxidative stress, which can otherwise damage or weaken mucous membranes. Its anti-inflammatory effects also support healing and comfort in irritated tissues, allowing natural lubrication processes to function optimally.

3. Enhancement of Lipid Barriers:  

The oils from sea buckthorn help restore the lipid (fatty) barriers of the skin and mucous membranes. This barrier is essential for trapping moisture and preventing excessive water evaporation, leading to improved hydration on the surface and within underlying tissues.

What Does the Science Say?  

Multiple clinical studies have explored the potential of Sea buckthorn oil for alleviating dryness:

- Vaginal Dryness:  

A landmark placebo-controlled study published in "Maturitas" (2014) followed postmenopausal women who took Sea buckthorn oil capsules daily for three months. Results showed significant improvement in vaginal moisture, elasticity, and overall comfort in the sea buckthorn group compared to placebo.

- Dry Eyes:  

Other studies, including research published in "Journal of Nutrition" (2010), have found that oral supplementation with Sea buckthorn oil improves tear secretion and reduces symptoms of dry eye, further substantiating its benefits for mucous membrane function.

- Skin and Mucosal Disorders:  

Sea buckthorn oil is also used topically and orally to support skin hydration and wound healing, with evidence suggesting improvement in skin barrier function and reduction in inflammation.

How to Use Sea Buckthorn for Moisture

Sea buckthorn supplements are available as capsules, oils, juices, and topical serums. For internal mucous membrane hydration (such as vaginal dryness, dry mouth, or dry eyes), oral supplementation with sea buckthorn oil—typically 500mg to 2000mg per day—has been shown to be effective and safe for most adults.

For external use (dry skin, minor wounds, or burns), direct application of pure sea buckthorn oil or a cream containing the oil can help restore skin hydration and barrier protection.

Considerations and Side Effects

Sea buckthorn is generally well tolerated. Mild digestive symptoms such as diarrhea can occur if consumed in excess. Individuals with allergies to the plant’s family (Elaeagnaceae) or those on blood-thinning medications should consult a healthcare provider before use. Always choose high-quality, pure sea buckthorn oils and supplements to maximize effectiveness and safety.

Conclusion

The reputation of sea buckthorn for making “wet” is well-founded from a scientific perspective. Its distinctive fatty acid composition, spearheaded by omega-7, provides direct support to the body’s mucous membranes, amplifying their ability to retain moisture and secrete natural lubricants. This has valuable benefits for managing dryness-related symptoms tied to menopause, aging, environmental factors, and certain medical conditions. As more clinical evidence accumulates, sea buckthorn remains a compelling, natural choice for those seeking holistic ways to restore internal and external hydration. Whether taken orally or used topically, sea buckthorn offers a unique and effective approach to a spectrum of dryness and lubrication concerns.
