美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I recently received a bottle of your 100% pure cold-pressed unrefined almond oil, and I noticed it states that it's not for internal use. I'm curious about the reason behind this label. Since this is sweet almond oil, I assumed it would be safe for consumption. Could you provide some insight into what makes this product unsuitable for internal use? I'm interested in understanding any specific processing methods or added ingredients that could pose a concern. Your clarification would be greatly appreciated!
