**Also Known As:** Ximenia americana, Olax subscorpioidea, False sandalwood bark, Plum bush bark, Hog plum bark

## Overview

Olacaceae bark extracts from Ximenia americana and Olax subscorpioidea contain high concentrations of procyanidins, catechin, and phenolic compounds that inhibit PGE₂ production by 47-68% and reduce [inflammatory](/ingredients/condition/inflammation) mediators TNF-α and IL-1β. These bioactive compounds demonstrate gastroprotective effects through nitric oxide pathways and sulfhydryl group mechanisms in preclinical studies.

## Health Benefits

- **Supports immune defense**: by enhancing the body's natural protective mechanisms.
- **Provides [antimicrobial](/ingredients/condition/immune-support) cleansing**: properties to combat various pathogens.
- **Aids in liver**: detoxification processes, promoting systemic purification.
- **Reduces [inflammation](/ingredients/condition/inflammation), contributing**: to overall comfort and well-being.
- **Fosters digestive balance**: by soothing the gastrointestinal tract.
- **Supports hormonal regulation**: through its influence on endocrine pathways.
- **Promotes skin healing**: and regeneration with its restorative properties.

## Mechanism of Action

Olacaceae bark's procyanidins B/C and catechin/epicatechin compounds inhibit [inflammatory](/ingredients/condition/inflammation) mediators including PGE₂ (47.92-67.78% reduction), TNF-α, and IL-1β through direct enzyme pathway interference. The bark's phenolic compounds activate gastroprotective mechanisms via sulfhydryl groups (-SH), nitric oxide (NO) production, and histidine decarboxylase inhibition. Additional antioxidant activity occurs through DPPH [free radical scaveng](/ingredients/condition/antioxidant)ing and TBARS lipid peroxidation reduction.

## Clinical Summary

Current evidence for Olacaceae bark comes entirely from preclinical animal and in vitro studies, with no human clinical trials completed to date. In animal models, Ximenia americana bark extract demonstrated 59.06% inhibition of chronic [inflammation](/ingredients/condition/inflammation) at 50 mg/kg doses and 61.79% histamine inhibition at 90 minutes. Olax subscorpioidea extracts showed antifungal activity with MIC values of 51.2 mg/mL against Aspergillus fumigatus and demonstrated safety in mouse toxicology studies. Human clinical trials are essential to validate these preliminary findings and establish therapeutic dosing protocols.

## Nutritional Profile

- Trace Minerals: Zinc, Copper, Iron
- Phytochemicals: Flavonoids, Triterpenes, Saponins, Tannins, Alkaloids, Phenolic compounds, Glycosides, Lignans

## Dosage & Preparation

- Common forms: Decoctions, extracts, tonics, elixirs, skin-cleansing formulations.
- Dosage: 300–600 mg/day extract or 1–2 tsp decoction daily, under supervision.
- Traditional application: Used for malaria, fever, worms, liver congestion, skin eruptions, purification rites, and postnatal care.

## Safety & Drug Interactions

Olax subscorpioidea methanol extracts demonstrated safety in mouse toxicological studies with no adverse effects reported at tested doses, though specific LD50 values remain undetermined. The high phenolic and triterpene content may cause gastrointestinal irritation at elevated doses, similar to other tannin-rich botanical extracts. Potential additive effects may occur with NSAIDs and [anti-inflammatory](/ingredients/condition/inflammation) medications due to shared PGE₂ inhibition pathways, requiring medical supervision for concurrent use. Use during pregnancy and lactation should be avoided due to insufficient safety data, and caution is advised with anticoagulant medications given the bark's [antioxidant](/ingredients/condition/antioxidant) properties.

## Scientific Research

Preliminary research, including in vitro and animal studies, suggests Olacaceae Bark's potential for [antimicrobial](/ingredients/condition/immune-support), [anti-inflammatory](/ingredients/condition/inflammation), and [hepatoprotective](/ingredients/condition/detox) activities. Further human clinical trials are required to validate its traditional uses and establish optimal dosages.

## Historical & Cultural Context

In ancestral forest medicine traditions across its native regions, Olacaceae Bark was viewed as a "guardian medicine" used in rites of purification and rebirth. The bark symbolized the shedding of toxins and reentry into vitality, revered for its role in fever-breaking, immune resetting, and ritual cleansing.

## Frequently Asked Questions

### What are the main active compounds in Olacaceae bark?

Olacaceae bark contains procyanidins B and C, catechin, epicatechin, flavonoids, lignans, triterpenes, and naphthoquinones as primary bioactive compounds. These phenolic compounds are responsible for the bark's anti-inflammatory and gastroprotective properties, with procyanidins showing the strongest activity in preclinical studies.

### How effective is Olacaceae bark for inflammation?

In animal studies, Olacaceae bark extracts reduced inflammatory markers PGE₂ by 47-68% and showed 59% inhibition of chronic paw edema at 50 mg/kg doses. The bark significantly reduced TNF-α and IL-1β levels (p<0.0001) and decreased leukocyte migration in pleurisy models, though human clinical validation remains pending.

### Is Olacaceae bark safe to use?

Preliminary toxicology studies in mice showed no adverse effects from Olax subscorpioidea extracts at tested doses, suggesting relative safety. However, the high tannin content may cause stomach irritation at large doses, and no human safety studies exist. Medical consultation is recommended, especially for those taking anti-inflammatory medications.

### What conditions does Olacaceae bark traditionally treat?

Traditional ethnomedicine uses Olacaceae bark for gastrointestinal disorders, inflammatory conditions, and as an analgesic remedy across African, Southeast Asian, and Central American cultures. The bark's gastroprotective effects work through nitric oxide pathways and mucus production enhancement, though these traditional uses require clinical validation.

### Can Olacaceae bark interact with medications?

Olacaceae bark may have additive effects with NSAIDs and anti-inflammatory drugs due to shared PGE₂ inhibition pathways, potentially increasing therapeutic or adverse effects. The bark's antioxidant properties suggest caution with anticoagulant medications, though no specific drug interactions have been documented. Medical supervision is recommended for concurrent pharmaceutical use.

### What is the best time of day to take Olacaceae bark supplement?

Olacaceae bark is typically taken with meals to enhance absorption and minimize potential gastrointestinal sensitivity, though timing can vary based on individual needs and product formulation. For immune and digestive support, many practitioners recommend taking it consistently in the morning or with your largest meal to maximize bioavailability. Always follow the specific dosage instructions on your supplement label, as preparation methods and concentration levels affect optimal timing.

### Is Olacaceae bark safe to take during pregnancy or while breastfeeding?

There is limited clinical data on Olacaceae bark use during pregnancy and breastfeeding, so it is generally recommended to consult with a healthcare provider before use during these periods. Due to its potent antimicrobial and detoxification properties, caution is warranted as these mechanisms may affect fetal development or breast milk composition. Pregnant and nursing women should prioritize established safety protocols and professional medical guidance before supplementing.

### How does Olacaceae bark compare to other immune-supporting bark supplements like pau d'arco or cat's claw?

While pau d'arco, cat's claw, and Olacaceae bark all support immune function, Olacaceae bark is uniquely valued for its combined liver detoxification and digestive soothing properties that complement immune defense. Pau d'arco is more traditionally recognized for antifungal activity, whereas Olacaceae bark provides broader antimicrobial spectrum coverage alongside systemic purification. The choice between them depends on whether your primary goal is immune support alone or a more comprehensive approach that includes digestive and hepatic benefits.
