## Overview

Calophyllum inophyllum nut oil contains 15-20% resinous bioactive compounds including calanolide A and B, which demonstrate complete HIV-1 reverse transcriptase inhibition at 5.9 ± 1.9 μM. The oil's 70-80% lipid content provides [anti-inflammatory](/ingredients/condition/inflammation) effects through pyranocoumarins like tamanolide while inhibiting [lipid peroxidation](/ingredients/condition/antioxidant).

## Health Benefits

- Promotes skin hydration and elasticity through its rich content of oleic and linoleic acids.
- Reduces skin [inflammation](/ingredients/condition/inflammation), offering soothing and calming effects.
- Protects the skin from oxidative damage due to its tocopherol (Vitamin E) content.
- Provides [antimicrobial](/ingredients/condition/immune-support) benefits, supporting wound healing and skin purification.
- Aids in cellular regeneration, contributing to scar and stretch mark reduction.

## Mechanism of Action

Calanolide A and B function as non-nucleoside reverse transcriptase inhibitors by directly blocking the HIV-1 reverse transcriptase enzyme. Tamanolide and related pyranocoumarins suppress [inflammatory pathway](/ingredients/condition/inflammation)s while providing cytoprotective effects in cellular models. The oil's [antioxidant activity](/ingredients/condition/antioxidant) occurs through direct inhibition of lipid peroxidation processes.

## Clinical Summary

Calanolide A demonstrated complete protection against HIV-1 replication with an IC₅₀ of 5.9 ± 1.9 μM in laboratory studies conducted by the National Cancer Institute. Ethanolic extracts of C. inophyllum seeds showed antiarthritic activity in rat models, indicating bioavailability of active phytoconstituents. Most clinical evidence remains at the preclinical stage, with limited human trial data available. The research foundation is strongest for [antiviral](/ingredients/condition/immune-support) properties, while dermatological applications rely primarily on traditional use and in vitro studies.

## Nutritional Profile

- Monounsaturated Fatty Acids (Oleic Acid)
- Polyunsaturated Fatty Acids (Linoleic Acid)
- Vitamin E (Tocopherols)
- Phytochemicals: Calophyllolide ([antimicrobial](/ingredients/condition/immune-support) compound)

## Dosage & Preparation

- Primarily used topically as an oil.
- Applied directly to the skin to treat burns, scars, stretch marks, and [inflammation](/ingredients/condition/inflammation).
- Commonly incorporated into massage oils, lotions, creams, and hair care products.

## Safety & Drug Interactions

Current research literature lacks comprehensive safety data for Calophyllum nut oil, including adverse effects, drug interactions, and contraindications. Given the potent bioactive compounds like calanolides, consultation with healthcare providers is essential before use, especially for individuals on antiretroviral medications. Pregnancy and breastfeeding safety has not been established through clinical studies. Topical applications may cause allergic reactions in sensitive individuals, requiring patch testing before widespread use.

## Scientific Research

Scientific research on Calophyllum Nut oil supports its traditional uses, highlighting its [anti-inflammatory](/ingredients/condition/inflammation), [antimicrobial](/ingredients/condition/immune-support), and wound-healing properties. Studies often focus on its unique fatty acid profile and bioactive compounds like calophyllolide, confirming its potential in dermatological applications.

## Historical & Cultural Context

In traditional medicine of the Pacific Islands, Calophyllum Nut oil has been revered for centuries for its powerful healing properties. Indigenous communities relied on it for treating wounds, cuts, burns, [inflammation](/ingredients/condition/inflammation), and for pain relief, establishing its profound cultural significance.

## Frequently Asked Questions

### What are the main active compounds in Calophyllum nut oil?

Calophyllum nut oil contains 15-20% resinous bioactive compounds including calanolide A and B, tamanolide, and tamanolides D and P. The remaining 70-80% consists of lipids rich in oleic and linoleic acids, along with sterols, coumarins, triterpenoids, and flavonoids.

### How effective is Calophyllum nut oil for skin healing?

Laboratory studies demonstrate antimicrobial and anti-inflammatory properties that support wound healing, primarily through tamanolide compounds and lipid peroxidation inhibition. However, human clinical trials specifically measuring skin healing outcomes are limited. Traditional use and in vitro studies suggest benefits for cellular regeneration and scar reduction.

### Can Calophyllum nut oil help with HIV treatment?

Calanolide A isolated from Calophyllum nuts showed complete protection against HIV-1 replication at 5.9 ± 1.9 μM in National Cancer Institute research. While these laboratory results are promising, the compound has not completed human clinical trials for HIV treatment. This research remains at the preclinical stage.

### What is the difference between Calophyllum and Tamanu oil?

Calophyllum nut oil and Tamanu oil are the same product extracted from Calophyllum inophyllum seeds. Tamanu is the traditional Polynesian name for this oil, while Calophyllum refers to the botanical genus name. Both terms describe the same therapeutic oil with identical bioactive compound profiles.

### Is Calophyllum nut oil safe for daily skin use?

While traditionally used for generations in Pacific Island medicine, comprehensive safety data for daily topical use is lacking in current research literature. The oil contains potent bioactive compounds that may cause allergic reactions in sensitive individuals. Patch testing and healthcare provider consultation are recommended before regular use, especially for those with skin sensitivities.

### Is Calophyllum nut oil safe to use during pregnancy and breastfeeding?

While Calophyllum nut oil is generally considered safe for topical use, pregnant and breastfeeding women should consult their healthcare provider before incorporating it into their routine, as systemic absorption and effects on the fetus or infant have not been extensively studied. Topical application in small amounts is typically lower-risk than oral supplementation during these sensitive periods. It is advisable to perform a patch test first and discuss with a healthcare professional before regular use.

### Can Calophyllum nut oil interact with topical medications or acne treatments?

Calophyllum nut oil may interact with certain topical treatments, particularly those containing retinoids, benzoyl peroxide, or strong exfoliants, as combining occlusive oils with these active ingredients can alter efficacy or increase irritation. If you are using prescription acne medications or vitamin A derivatives on your skin, it is best to apply Calophyllum oil at different times of day or consult a dermatologist before combining them. Patch testing is recommended when introducing any new product to an existing skincare regimen.

### What is the most effective form of Calophyllum nut product—pure oil, infused creams, or capsules?

Pure Calophyllum nut oil (also called Tamanu oil) is considered the most potent and bioavailable form for topical skin benefits, as it delivers the full spectrum of active compounds directly to affected areas without dilution. Infused creams and lotions offer convenience and may be easier to apply to the face, but they typically contain lower concentrations of the active ingredient due to other base ingredients. Capsules or oral supplements are less commonly used and have limited research on internal absorption and efficacy compared to topical application.
