Ratih is the Javanese moon goddess — wife of Kamajaya, the god of love. The Javanese equivalent of the Hindu Rati. Ratih and Kamajaya are the iconic couple of Javanese mythology, representing ideal love.
Ratih is widely used in Indonesia.
Ratih does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Ratih reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
