Derived from the berries and leaves of the Hippophae rhamnoides plant, sea buckthorn tea is a nourishing infusion that offers both a tart, citrusy flavor and a long list of potential health benefits.

In this article, we’ll dive deep into what sea buckthorn tea is, explore its impressive nutritional profile, look at both the health benefits and side effects, learn how to prepare it properly, get creative with delicious recipes, and offer tips on where to buy high-quality sea buckthorn tea.

What Is Sea Buckthorn Tea?

Sea buckthorn tea is an herbal infusion made from the leaves, berries, or both parts of the Hippophae rhamnoides plant, commonly known as sea buckthorn. This resilient shrub is native to parts of Europe and Asia, thriving in salty, dry, and even mountainous soils. It has been used for centuries in traditional medicine, particularly in Tibetan, Mongolian, and Russian herbal healing systems.

The tea can be made in a few different ways—using dried berries for a tangy, fruity flavor, or steeping the leaves for a more earthy, grassy taste. Some blends even combine both for a fuller, more balanced experience. The berries themselves are famously bright orange and are known to be one of the most nutritionally dense fruits on Earth.

Historically, sea buckthorn has been used to promote cardiovascular health, aid digestion, and heal skin ailments. Modern interest in this herbal tea has surged due to its rich content of antioxidants, essential fatty acids, and immune-boosting vitamins.

• Omega-7 also supports tear production and may help with dry eyes.

Potential Side Effects and Precautions

While sea buckthorn tea offers an impressive list of health benefits, it’s important to be aware of its potential side effects and interactions—especially for those with underlying health conditions or who are pregnant.

Digestive Upset in Sensitive Individuals

• Some people may experience mild gastrointestinal discomfort, such as cramping, diarrhea, or bloating after drinking sea buckthorn tea, especially in large quantities.
• This is more likely if the tea is made from the berries, which are quite tart and fibrous.

Not Recommended During Pregnancy and Breastfeeding

• Pregnancy and sea buckthorn tea is a debated topic. While there’s no conclusive evidence that it causes harm, there’s also insufficient research to confirm its safety for pregnant or breastfeeding individuals.
• Due to its bioactive compounds and potential hormonal effects, it’s best to avoid sea buckthorn tea during pregnancy unless cleared by a healthcare provider.

Possible Interaction with Medications

• Sea buckthorn may interact with blood-thinning medications (like warfarin) due to its omega-7 and vitamin E content, which can naturally thin the blood.
• It may also influence blood sugar and blood pressure levels, so individuals taking medications for diabetes or hypertension should monitor their response carefully.

Allergic Reactions

• Though rare, allergic reactions such as skin rash, itching, or swelling can occur in people sensitive to sea buckthorn or similar plants.
• Start with a small amount to assess tolerance if trying sea buckthorn tea for the first time.

Long-Term Use and Dosing Caution

• While the tea is generally safe for short-term use, there is little data on the effects of long-term daily consumption in high doses.
• Stick to 1–2 cups per day unless advised otherwise by a health professional.

As with any herbal supplement, consult your doctor before introducing sea buckthorn tea—especially if you’re on medications, pregnant, or managing a chronic condition.
