In ancient herbalism, great attention was paid to the protocol for picking plants. There are still some surviving texts purely about this topic:
- Theophrastus on Picking Plants: a critical discussion of observances.
- For Picking Plants: a simple and generic ritual from the Greek Magical Papyri.
- Prayer to the Earth and All Herbs: another set of words to say while picking plants.
Other texts contain such information more or less incidentally:
- Poem On Herbs: mostly gives information about when to pick the plants.
