By single syllables of an unknown ingredient Salsearch can detect an existing salicylate danger. The additives oil, extract, etc., lead to a valuation with "minus points". The automatic evaluation works pretty reliable - but it can occasionally happen that a really salicylate free ingredient is rated as “contains salicylate”. The search engine is evaluating rather "over-cautious".
As "verified manually" marked results have been explicitly evaluated by a human and are reliable.
