Which body types are not suitable for consuming Ejiao (donkey-hide gelatin)?

The following groups of people should consume donkey-hide gelatin (Ejiao) cautiously or avoid it altogether:

1. Individuals with damp-heat constitution: These individuals typically experience symptoms such as a yellow, greasy tongue coating, bitter taste in the mouth, and sticky bowel movements due to excessive internal dampness. Ejiao has a rich and greasy nature that may exacerbate dampness and heat, worsening these symptoms.

2. Individuals with weak spleen and stomach: Ejiao is rich and greasy in nature, making it difficult to digest. Consumption by those with weak digestive systems may burden the spleen and stomach, potentially causing indigestion, poor appetite, and related symptoms.

3. Individuals with colds or fever: During a cold, the body's defensive energy is engaged in fighting pathogenic influences. At such times, overly nourishing substances should be avoided, as they may "lock the door and keep the invader inside," hindering the elimination of pathogenic factors.

4. Individuals with blood-stasis constitution: Although Ejiao has functions of nourishing yin and enriching blood, excessive nourishment may increase blood viscosity in individuals with a blood-stasis constitution, thereby impairing circulation.

5. Individuals with allergic constitutions: Some people are allergic to the protein components in Ejiao, and may experience allergic reactions such as rashes and itching after consumption.

6. Patients with hypertension or diabetes: Ejiao contains a high amount of sugar, which may interfere with blood pressure control in hypertensive patients, and cause blood glucose fluctuations in diabetic patients, both of which are detrimental to disease management.
