Tools
Every calculator, calendar and studio in one place — from garden to formula to finished product. Filter by what you need, or search by name. Bigger engines (IFRA, costing, labels, the AI co-pilot, plant safety, the SDS reader) live inside the
Formula Lab,
Plants and
Grow.

Self-check, not certification. Urður's tools are professional design aids for herbal supplements, growing & natural cosmetics — not medicine, not a legal safety assessment.
