Ethical Harvesting

The ethical harvesting of black nightshade (Solanum nigrum) requires careful and respectful practices to preserve the plant and its natural environment, as well as to ensure its availability for future medicinal and spiritual uses. Harvest only the necessary amount, avoiding excessive extraction that could weaken or significantly reduce the wild population. Preferably cut the upper parts of the plant, such as leaves and young branches, without uprooting the entire plant or damaging its roots, to allow for rapid regeneration.
