In May 2009, she was left leg paralyzed for 6 months due to Lumbar 4&5 foraminal stenosis (the narrowing of the intervertebral opening through which the sciatic nerve roots travel, which compresses or irritates the sciatic nerve). Specialists from National University Hospital (NUH) had suggested to insert 2 screws, but she refused after learning from experienced patients with screws inserted that they had not wholly recovered physically. She took advise from her sister, Yonie Bonawi, to do Raindrop Technique Therapy with Young Living essential oils and Jin Shin Jyutsu body energy healing technique, and she has completely healed since then.

She was fascinated with the immediate recovery that it inspired her to enrol as a Young Living member and took up courses with Jin Shin Jyutsu, along with other alternative healing courses and has been practising since then. After learning Iridology, Sclerology & Glyphology, she has incorporated the knowledge into her practice.

She has been teaching and sharing Jin Shin Jyutsu self-help mostly in Malaysia & Singapore, giving talks and hosting online video conferences discussing topics like Mindful Breathing, My Healing Journey, and Supporting Mental Health.

Currently, Yohana works mostly with young & old with various conditions.
