To ensure safe use, it is advisable to consult a healthcare professional, start with small doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Portulaca oleracea grows best in well-drained soil with a pH between 6.0 and 7.5, preferring full sun to partial shade and moderate watering to avoid waterlogging.

It thrives in warm climates and requires regular but careful watering, as overwatering can lead to root rot. For optimal growth, it should be planted in spring after the last frost, and it benefits from occasional fertilization with a balanced organic fertilizer. Harvesting is best done in the morning when the plant is most hydrated, using sharp scissors to cut the leaves and stems just above the node to encourage regrowth.

To preserve its potency, the harvested plant should be dried in a shaded, well-ventilated area or in a dehydrator, then stored in airtight containers in a cool, dark place to maintain its medicinal properties.
