Forms, Preparation and Usage

Aesculus hippocastanum has been traditionally used in herbal medicine for its purported cardiovascular and anti-inflammatory properties, with various forms available including fresh leaves, dried tincture, powder, essential oil, and capsules.

Preparations can be made as a tea by steeping dried leaves in hot water, or as a decoction by boiling them for a longer period, while topical applications involve using a diluted tincture or powder directly on the skin. For internal use, the recommended dosage for adults is typically 1-2 ml of tincture or 1-2 grams of powder three times daily, though children should only use it under strict medical supervision if deemed safe.

It is advised to use aesculus hippocastanum for short durations, no longer than two weeks, to minimize potential toxicity, and to consult a healthcare professional before prolonged use.

Safety, Side Effects and Contraindications

Aesculus hippocastanum can be used with caution due to its potent effects and potential toxicity.

It may cause side effects such as nausea, vomiting, diarrhea, dizziness, and in severe cases, cardiac arrhythmias or paralysis due to its high levels of saponins and cardiac glycosides. It should not be used by pregnant or breastfeeding women, as it can cause fetal harm or be excreted in breast milk. Individuals with chronic illnesses, particularly heart conditions, should avoid it due to the risk of exacerbating cardiovascular issues.

To ensure safety, always consult a healthcare provider before use, start with low doses, and avoid long-term or excessive use.

Growing, Harvesting and Storage

Aesculus hippocastanum grows as a slow-growing deciduous tree or shrub, typically reaching heights of 10 to 20 feet, and thrives in full sun to partial shade with well-drained, loamy soil that is slightly acidic to neutral.

It requires regular watering during its establishment phase, though it becomes drought-tolerant once mature, and benefits from mulching to retain moisture and suppress weeds. For optimal growth, regular pruning is recommended to maintain shape and promote air circulation, while fertilizing in early spring with a balanced fertilizer can enhance its vigor and flowering. The medicinal parts, primarily the seeds and bark, are harvested in late summer to early autumn when the fruits are mature and the seeds are hard and fully developed, using a pruning shear or hand tools to collect the dried pods.

To preserve potency, the harvested seeds should be thoroughly dried in a well-ventilated area, then stored in airtight containers in a cool, dark, and dry place, or refrigerated for longer shelf life.
