Summary of Key Points
  • Sea buckthorn (Saji) is a treasure trove of nutrients, including Omega-3, 6, 7, and 9. Notably, Omega-7 (palmitoleic acid) accounts for approximately 30-35% of the fruit's fatty acids.
  • Research suggests that flavonoids like quercetin may offer antioxidant benefits, supporting cardiovascular health and reducing inflammation.
  • While beauty and health benefits such as suppressing rapid blood sugar spikes, supporting liver function, and promoting skin regeneration are suggested, it's important not to have excessive expectations.
  • Consumption can be in oil form (edible or topical) or capsules. Aim for 1-2 teaspoons per day, and consult a doctor if you are taking medication.

What kind of plant is Sea Buckthorn (Saji)? Introduction and Background

Sea buckthorn is a shrub that grows in high-altitude regions like the Himalayas, and the oil extracted from its orange berries has been used for centuries in traditional Chinese medicine and Ayurveda as the "sacred fruit of the Himalayas." Our research reveals that its leaves, fruits, and seeds are rich in vitamins (including B-group vitamins like folic acid and biotin, and vitamin E), minerals such as potassium and calcium, and various fatty acids. Recent studies (such as reports from Lipids in Health and Disease) have also highlighted the abundance of its components.

Nutritional Characteristics: The Spotlight on Omega-7 (Palmitoleic Acid)

The prominent feature of sea buckthorn oil is that it contains four types of unsaturated fatty acids: Omega-3, Omega-6, Omega-7, and Omega-9. Among these, Omega-7 (palmitoleic acid) is reported to account for approximately 30-35% of the total fatty acids in the fruit and is believed to act on the metabolism of the liver, blood vessels, and skin. Additionally, it is rich in antioxidant components such as flavonoids like quercetin and tocopherols, which are expected to reduce oxidative stress in the body. These points are also noted in PubMed research and nutritional analysis reports.

Expected Health Benefits — Scientific Evidence and Practical Use

Cardiovascular Support

Flavonoids like quercetin may positively influence blood pressure and blood lipids through their antioxidant and anti-inflammatory effects, potentially leading to a reduction in heart disease risk. However, the strength of the effect and clinical significance vary among individuals, so it's realistic to understand that it "may be helpful as a supplement."

Potential for Improving Blood Sugar and Metabolism

Some studies suggest that sea buckthorn may have the effect of slowing down the rise in blood sugar after meals and positively influencing fat metabolism. It is expected to be a supplement for diabetes prevention, but if you are taking medication, please consult your doctor for managing the risk of hypoglycemia.

Liver Function and Antioxidant Effects

Antioxidant components have been reported to have a protective effect on the liver, and some studies have shown improvement in liver function markers. However, it is important to avoid definitive statements like "dramatically cures" and to use it in conjunction with lifestyle improvements.

Beauty Uses: Effects on Skin and Hair, and Our Personal Experience

Sea buckthorn oil is attractive because it can be used both internally and externally. It is expected to promote skin regeneration and moisturizing effects, and there are reports that it reduces inflammation and aids in wound healing. When we actually incorporated a small amount into our nighttime skincare routine, we were surprised to find that the suppleness of dry, rough areas improved and our skin gained a glow. However, some products have strong scents and colors, so we recommend doing a patch test when using it for the first time. Examples of use: - Edible: Mix 1 teaspoon (approx. 5ml) into yogurt or smoothies - Supplements: Follow the instructions on capsule products - Topical: Apply 2-3 drops to the face after toner (can be used only at night)

Precautions and How to Choose

The active ingredients vary depending on the product and extraction method. Products labeled as extra virgin or cold-pressed are good indicators of quality. Also, please note the following: - Consult a doctor if you are taking medication (anticoagulants, antihypertensives, diabetes medications, etc.) - Consult a doctor as safety during pregnancy and lactation has not been sufficiently confirmed - Discontinue use if allergic reactions or digestive symptoms (diarrhea, stomach upset) occur - For use in children, follow product instructions or a doctor's advice We recommend starting with half a teaspoon and gradually increasing while monitoring your physical condition. It is reassuring to choose products from reliable manufacturers that publish third-party analysis lab results.

Summary

Sea buckthorn contains a variety of nutrients, including Omega-7, and is a plant that may have positive effects on cardiovascular, metabolic, liver, and skin health. In our experience, we felt the skincare effects and found some edible varieties with a pleasant flavor that were easy to continue using. On the other hand, the effects vary among individuals, and those taking medication or with specific health conditions should consult a doctor before incorporating it. As a supplementary health and beauty item, incorporating it into your daily diet and skincare without overdoing it is the most sensible approach.
