In homeopathy, Thuja Occidentalis (commonly known as Thuja) is associated with a personality that is introspective, sensitive, and often feels a sense of fragility. Here are some key characteristics:

1. Introversion and Withdrawal: Thuja individuals tend to be introspective and may withdraw emotionally, feeling a sense of isolation.
2. Sensitivity and Vulnerability: They are highly sensitive to emotions and external stimuli, and may feel easily hurt.
3. Fixed Ideas and Delusions: Thuja personalities often have rigid thought patterns and may hold onto fixed ideas.
4. Secretiveness: They may be secretive and conscious of their image, fearing exposure of their perceived flaws.
5. Empathy and Compassion: Despite their vulnerabilities, Thuja individuals often have a deep understanding of others’ feelings and show empathy.
6. Perfectionism: They may have a tendency towards perfectionism, paying great attention to detail.
7. Commitment to Personal Growth: Their introspective nature leads to a strong commitment to personal growth and self-improvement.

Thuja personalities often present a strong front to the outside world but may feel unhappy and negative deep down.
