Theriso BotanicsPurity and Concentration Criteria
A botanical extract is a solution of active compounds in a liquid carrier. Effectiveness depends on the plant part, the extraction ratio, and the solvent quality. For Cretan herbs such as dittany and malotira, harvesting at the correct flowering stage determines terpene concentration.
Technical Details on the Label
Always check the extraction ratio on the label. A 1:5 ratio means one part dry herb to five parts solvent.
- Extraction ratio: Choose preparations with a stated ratio of 1:3 for fresh herb or 1:5 for dried material.
- Solvent type: Pharmaceutical-grade ethyl alcohol and deionized water keep phenols stable.
- Light protection: Dark amber glass prevents the breakdown of light-sensitive compounds by ultraviolet rays.
Common Selection Mistakes
Many commercial products use clear plastic. Plastic allows oxygen and light to pass through, causing the formula to oxidize within a few weeks. Avoid extracts that lack the plant botanical name, such as Origanum dictamnus or Sideritis syriaca.
Proper Use and Storage
Keep the bottle tightly closed in a cupboard at a temperature below 22 degrees Celsius. Use the dropper without touching your mouth or skin to prevent bacteria from entering the liquid.
