Hista Block Tablets is a herbal Ayurvedic and Siddha formula with Ashwagandha, Amla and Sariva. Traditionally taken to support skin comfort and the body's natural balance through the seasons.
Hista Block Tablets, formerly known as G7 capsules, is a herbal formula from the Ayurvedic and Siddha traditions, built around Ashwagandha, Amla, Sariva and Clerodendrum. It is traditionally taken to support skin comfort, to calm the sensation of itching, and to support the body's natural balance through changing seasons.
These herbs are classical choices for the skin and for the body's seasonal resilience.
Ayurvedic Significance
In Ayurveda, skin comfort is closely tied to balanced Pitta and healthy Rakta (blood), while the body's response to seasonal change is supported by strong Ojas. Cooling, blood-supporting herbs such as Amla and Sariva, together with the Rasayana Ashwagandha, are traditionally used for this purpose.

+What is it traditionally valued for?
It is traditionally valued for helping to steady the mast cells and calm the histamine release that drives allergic itching and inflammation, supporting relief in allergic skin conditions such as dry eczema, without drowsiness. These are traditional, supportive uses; it is not a substitute for emergency treatment of a serious allergic reaction.
+When is urgent care needed?
Seek urgent medical help for any allergic reaction with swelling of the lips, tongue, or throat, difficulty breathing, or faintness, as this can be life-threatening (anaphylaxis). For persistent, widespread, or severe eczema or allergy, see a doctor or dermatologist. Those pregnant, breastfeeding, or on medication should check with a doctor first.
