Martin has to deal with PC Mark Mylow's sister Sandra, a naturopath who has returned to Portwenn selling her natural remedies. Martin's effort to have her consult before "prescribing" any of her concoctions falls on deaf ears. Martin also has to deal with a odd family where the father is a bit of a ruffian and his two adult sons are in fear of him. They obviously rely on their mother to calm the home situation, but Martin is concerned when he observes that she is kept locked in a room to which he is refused admission. Al Large and receptionist Pauline start dating and a chance remark on the colour of his eyes leads him to believe that Bert may not be his biological father. Aunt Joan helps Al deal with his doubts.

"It's's herbal."
22 April 2015 | by (Bradenton, Florida) – See all my reviews

"Blood is Thicker" is an excellent episode of "Doc Martin", as it's written a bit better than usual and holds your interest. I know this is the case, as my older daughter is usually indifferent towards the program and really enjoyed this one.

Like other episodes, there are several plots running through this one. One, the slightest of the plots, involves a man who wonders about his exact parentage, as he really doesn't look a lot like his father. This one is very touching and actually might make you look for a Kleenex. The more dominant plot is a naturopath who is in town prescribing all sorts of herbal elixirs with no real concern about how this might interact with the drugs prescribed by Doc Martin. She is actually MORE egotistical and disagreeable than the Doctor and for once you can understand how the Doc is outraged at the woman's lack of professionalism or consideration. This turns out to be a serious problem in the case of a VERY strange family where salmonella is NOT there most serious concern. I'd say more but it might spoil it, as there is a HUGE surprise!!

The bottom line is that this episode works a bit better than usual and the show is hitting its stride. However, if you love the idea of folk medicines and all sorts of unproven herbal remedies, you might be offended. The show, however, isn't so much anti- naturopathy but is stressing responsibility--and I have been alarmed at the dubious claims and lack of scientific rigor with these drugs (and yes, they are drugs). Well worth seeing.
