Botanical blends—including herbs such as chamomile, lavender, passionflower, and other calming plants—have a long history of traditional use to support emotional sensitivity, mood balance, and overall emotional well-being. These blends are often found in folk medicine and herbal traditions across multiple cultures, where they are used as teas, tinctures, or supplements to promote calmness and reduce irritability or emotional reactivity.

The rationale behind their use is primarily based on anecdotal evidence and centuries-old herbalism rather than robust clinical studies. For instance, chamomile and lavender have been traditionally used to soothe nervousness and support relaxation. Passionflower has a history of use for easing agitation. However, scientific research on multi-herb "botanical blends" specifically for emotional sensitivity is limited, and most available studies focus on single herbs or use "emotional sensitivity" as a loosely defined term. While some individual herbs in these blends have shown modest effects in reducing anxiety or supporting mood in small studies, direct evidence that botanical blends as a whole are effective for "emotional sensitivity" is lacking.

In summary, the use of botanical blends for emotional sensitivity is primarily justified by tradition, with low to moderate supporting evidence from scientific research on individual ingredients, but little direct clinical validation for the blended formulations or the specific claim of addressing "emotional sensitivity."
