Background
  • Korean pine (Pinus koraiensis) is a hardy evergreen tree with edible seeds, commonly called pine nuts or pine kernels, which are often used as an ingredient in pesto or cooking oils. Several parts of the Korean pine plant have been used medicinally, including the leaves, roots, bark, stems, and resin. The principal active ingredient is thought to be pinolenic acid. Pinolenic acid is not to be confused with columbinic acid found in columbine (Aquilegia vulgaris) seed oil.
  • In traditional Chinese medicine, Korean pine has been used for its cholesterol-lowering and appetite-suppressing effects. Additional studies are needed to confirm the safety and efficacy of its long-term use.

Evidence Table

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. GRADE *


Early research suggests that Korean pine nut oil decreases food intake and feelings of hunger. Additional long-term research in this area is needed.

B
* Key to grades

A: Strong scientific evidence for this use
B: Good scientific evidence for this use
C: Unclear scientific evidence for this use
D: Fair scientific evidence for this use (it may not work)
F: Strong scientific evidence against this use (it likley does not work)


Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

  • Allergic disorders, angina (chest pain), angiogenesis (new blood vessel growth), antibiotic, anti-inflammatory, antioxidant, antiperspirant, antitumor, arrhythmia (abnormal heart rhythm), autoimmune disorders, blood clots, blood thinner (viscosity), body fat reducer, cancer, cerebral ischemia (insufficient blood flow and oxygen to brain), cervical cancer, deafness, deodorant, dermatitis, diabetes, digestive aid, eye disorders (swelling of the cornea), gastrointestinal disorders, hair growth stimulant, hair loss (prevention), heart disorders, high blood pressure, high cholesterol, HIV (medication side effects), hyperlipidemia (high blood lipids), inflammatory conditions, keratitis (inflammation of the cornea), metabolic enhancement, nutritional deficiencies (fatty acid deficiency), senile dementia, skin disorders, stamina enhancer, weight loss/obesity.

Dosing

Adults (18 years and older)

  • For appetite suppression, single doses of 2-3 grams of PinnoThinT pine nut free fatty acid (FFA) oil and 2-6 grams of PinnoThinT pine nut triglyceride (TG) oil have been taken by mouth.

Children (under 18 years old)

  • There is no safe or effective dose for Korean pine in children.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

  • Avoid with known allergy or hypersensitivity to Korean pine (Pinus koraiensis), its constituents, or members of the Pinus genus or Pinaceae family. Pine seeds contain major food allergens. Severe acute allergy, angioedema (swelling under the skin), systemic hypotension (whole-body low blood pressure), shock, systemic allergic reactions, acute anaphylaxis (rapid-onset life-threatening allergic reactions), and heart attack have been reported. Cross-reactivity, sensitivity, and other reactions have been reported in individuals prone to allergies and in individuals with allergies to Artemisia vulgaris (mugwort or common wormwood), almonds, grass pollen, peanuts, olive pollen, pine pollen, or pine resin.

Side Effects and Warnings

  • Information on the long-term safety and efficacy of Korean pine (Pinus koraiensis) is lacking. The major adverse reactions due to Korean pine nut are related to allergies and hypersensitivities. Severe reactions such as shock and heart attack due to allergy to pine nut have been reported.
  • Use cautiously in individuals prone to allergies, in nonallergic children, in pregnant or breastfeeding women, or in high amounts.
  • Korean pine may increase the risk of bleeding. Caution is advised in patients with bleeding disorders or those taking drugs, herbs, or supplements that may increase the risk of bleeding. Dosing adjustments may be necessary.
  • Korean pine may cause low blood pressure. Caution is advised in patients taking drugs, herbs, or supplements that lower blood pressure.
  • Korean pine may lower lipid levels. Caution is advised in patients taking drugs, herbs, or supplements that lower lipid levels.
  • Avoid use in unsupervised children with other existing nut allergies.
  • Avoid with known allergy or hypersensitivity to Korean pine (Pinus koraiensis), its constituents, or members of the Pinus genus or Pinaceae family.

Pregnancy and Breastfeeding

  • Use cautiously in pregnant or breastfeeding women, due to a lack of available safety information. In nonallergic women, Korean pine nuts are likely safe when taken in amounts typically found in foods.

Interactions

Interactions with Drugs

  • Korean pine may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin®) or heparin, antiplatelet drugs such as clopidogrel (Plavix®), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
  • Korean pine may cause low blood pressure. Caution is advised in patients taking drugs that lower blood pressure.
  • Korean pine may also interact with antibiotics, anticancer agents, antifungals, lipid-lowering agents, and weight loss agents (such as agents similar to glucagon-like peptide-1 (GLP-1)).

Interactions with Herbs and Dietary Supplements

  • Korean pine may increase the risk of bleeding when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Gingko biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
  • Korean pine may cause low blood pressure. Caution is advised in patients taking herbs or supplements that lower blood pressure.
  • Korean pine may also interact with antibacterials, anticancer herbs and supplements, antifungals, lipid-lowering herbs and supplements, and weight loss herbs and supplements.
