Withania somnifera Side effects
Increased hotness, gastritis:
If used alone, for example, Ashwagandha capsule with water, it tends to worsen gastritis in people with sensitive stomach. It also causes constipation in a few.
Because of its innate hot nature, people with Pitta dominance, feel increased hotness with Ashwagandha capsule.
But if it is taken along with milk or ghee, usually this side effect is very much nullified.

Sedative effect: In a very high dose, it may have sedative effect. Hence some experts advice to avoid it during day. But I have not seen its sedative effect so big to put someone to sleep in the day time. However, it is best to take it in the day, only if your doctor has suggested so. Its sleep promotion effect can be more attributed to its anti anxiety and anti depression properties than to its sedative effect.
It can be used safely in children and lactating mother, under medical supervision.
It is best to avoid this during pregnancy.

Ashwagandha churna Vs Ashwagandha capsule
When pure uncontaminated Ashwagandha churna is available, then it is usually preferred to capsule form. But usually Churnas get contaminated easily.
When Ashwagandha needs to me formulated as a mix powder along with other powders (such as Ashwagandhadi Churna, used in indigestion), powder form has advantage over the capsule form.
Ashwagandha capsule is usually prepared with its water extract or crude extract, which retains most of its chemical constituents.
When it comes to easy dosage fixing and easy consumption, capsule is lot better than Churna form, because of bitter taste of Ashwagandha and powder dose fixing is a bit difficult task.
If Ashwagandha alone is to be used for treatment, then capsule can be preferred. But if used alone with water, it tends to cause burning sensation in stomach, hence it is advisable to use it along with milk or ghee, or a combination of both.
